ABSTRACTBackgroundIndividuals with psychosis symptoms are at high risk for suicidal ideation and attempts. The prevalence and correlates of suicidal ideation and attempts in clinical high risk for psychosis (CHR‐P) have yet to be clarified. This study reports on the prevalence and clinical correlates of suicidal ideation and attempts in a clinical CHR‐P sample.MethodParticipants (n = 135) included CHR‐P clients at a CHR‐P community specialty clinic, who participated in a clinical assessment between 2017 and 2022. Assessments measured attenuated psychosis symptoms, suicidal ideation and attempts, clinical covariates, and functioning. Frequency analyses assessed the prevalence of lifetime suicidal ideation and attempts and t‐test and Chi‐square identified clinical correlates. Logistic regression assessed the relationship between significant clinical correlates and lifetime suicide attempts.ResultsSixty‐five percent of participants at CHR‐P endorsed lifetime suicidal ideation, while 22.2% reported at least one lifetime attempt. Correlates for lifetime suicidal ideation included self‐reported gender expansive identity, hopelessness, depression, trauma, obsessive compulsive symptoms, insight: reflectiveness, trauma diagnoses, mood disorder diagnoses, and perceptual abnormalities/hallucinations. Significant correlates for lifetime suicide attempts included self‐reported hopelessness, depression, trauma diagnosis and mood disorder diagnosis.ConclusionCHR‐P clients are at a higher risk for suicidal ideation and attempts compared to the general population. Correlates of suicidal ideation and attempts may be diagnostically heterogeneous and therefore interventions should be tailored to specific clinical needs. Clients with trauma‐disorder diagnoses may be at highest risk for suicidal ideation and attempts. Continued intervention and longitudinal research is needed to clarify causal risk factors and establish evidence‐based treatments for suicidal ideation and attempts in CHR‐P.

Published: December 2024

ABSTRACTA knowledge gap exists regarding the faculty's dynamic selection and modification of emotion regulation strategies to reduce negative emotions in synchronous teaching. This study conducted semi‐structured interviews with 16 teachers at higher education institutions in China, focusing on their handling of the negative emotions that arose from poor teacher–student interactions. Technology‐induced and student‐induced behaviour problems are two primary causes of faculty's negative emotions. The problem‐focused emotion regulation strategy effectively reduced faculty's negative emotions when facing the former. In handling student‐induced negative emotions, the problem‐focused strategy was only occasionally sufficient. The ownership of synchronous teaching provides faculty with continuous agency to reflect on teaching challenges. The outcome of this reflection enables faculty to alter emotion regulation strategies and ultimately reduce negative emotions without compromising students' rights. We propose that critical reflection that challenges underlying assumptions (e.g., double‐loop learning) can effectively mitigate negative emotions while ensuring equitable online education.
Drawdown minimization in asset portfolio selection: MINLP models and efficient cross‐entropy algorithm
Authors: Bayat M. , Hooshmand F. , MirHassani S.A. 
Published: December 2024

AbstractPortfolio management is an important research topic in finance and optimization. Drawdown as one of the measures in evaluating portfolios indicates the relative difference between the portfolio value in the current moment and its maximum value during a given time interval in the recent past. In this paper, first, the importance of this measure is discussed and then two mixed‐integer nonlinear programming (MINLP) models with the objectives of minimizing the expected drawdown and the maximum drawdown under real‐world constraints are presented. Due to the NP‐hardness of this problem, by utilizing the problem structure, an efficient cross‐entropy‐based algorithm is presented to solve it. An effective mechanism is suggested to calibrate the algorithm parameters. Computational results confirm the performance of the proposed algorithm from both solution quality and running time in comparison with MINLP solvers.
In tech we rely: How technology dependence fuels consumer vulnerability

Published: December 2024

AbstractUnderstanding and mitigating consumer vulnerability is critical in an age of pervasive misinformation and deception. This research examines how technology dependence can heighten consumer vulnerability by elevating the risk of being deceived in the marketplace. Drawing from Human‐Computer Interaction (HCI) research and Media Systems Dependency Theory (MSD), we propose that high technology dependence depletes cognitive resources, reduces consumer skepticism, and increases susceptibility to deception, an essential element of consumer vulnerability. Through three empirical studies, we show that technology dependence heightens consumers' vulnerability to deceptive information, primarily through reduced skepticism. Furthermore, we found that consumers' moods moderate this relationship, with negative moods mitigating and positive moods amplifying the adverse effects of technology dependence on skepticism. Our findings reveal mechanisms driving consumer vulnerability in the digital age, offering valuable insights for marketers and policymakers to enhance consumer protection, as well as marketplace and digital literacy.

Published: December 2024

ABSTRACTBackgroundThe dermal extracellular matrix (ECM) is a dynamic scaffold composed mainly of proteins, with collagen as the key structural component providing resilience and support to the skin. Post‐menopause, declining estrogen levels lead to a significant reduction in skin health, notably a 30% decrease in collagen types I and III within 5 years.AimTo discover natural extracts that stimulate collagen production.MethodsWe utilized PathwayStudio to analyze protein–protein interactions and identify regulators of essential collagen types. Our study assessed Glycyrrhiza uralensis extract's ability to boost collagen production and enhance dermal density both in vitro and in vivo.ResultsPathwayStudio analysis highlighted phytoestrogens including glycyrrhizin, isoliquiritigenin, liquiritigenin, liquiritin, and glabrol, as potential candidates. Liquorice rhizome (G. uralensis), used in traditional Chinese medicine, is rich in phytoestrogens like liquiritigenin. The G. uralensis extract increased collagen I and III gene expression and pro‐collagen I protein levels in human dermal fibroblasts and inhibited UVB and pollution‐induced matrix metalloproteinase‐1 (MMP1) production. In an in vivo study, a topical formulation containing the extract significantly improved dermal density after 56 days, measured by the DUB SkinScanner.ConclusionsThese findings suggest G. uralensis extract as a promising agent for enhancing collagen production and skin health, particularly in postmenopausal women. Further research is needed to explore its mechanisms and long‐term effects.

ABSTRACTAimThis study aimed to explore the risk factors related to home‐based operation management leading to the occurrence of peritoneal dialysis‐associated peritonitis (PDAP).DesignAn observational research was conducted.MethodsA retrospective analysis was conducted among patients with maintenance peritoneal dialysis (PD) between 1 January 2019 and 31 December 2022. The patients were grouped according to the occurrence of PDAP. General characteristics and home operational data were collected and logistic regression analysis was performed to identify independent risk factors for PDAP associated with home operations. This study complied with the Appendix S1.ResultsOf 458 PD patients included in this study, 82 were in the peritonitis group. Their average age was 53.34 ± 13.62 years, and the average dialysis vintage was 35.57 ± 32.74 months, with males accounting for 54.6%. Multivariate logistic regression analysis revealed that age; primary disease, such as diabetes mellitus; dialysis vintage; improper storage of dialysis fluid; failure to verify the quality of protective‐caps with povidone‐iodine; and improper handwashing were risk factors of PDAP. Daytime ambulatory PD mode was significantly negatively associated with PDAP.ConclusionImproper storage of dialysis fluid, failure to check the quality of protective‐caps and improper handwashing at home are independent risk factors for PDAP caused by home‐based operation management. Nurses should strengthen relevant training or retraining to address this.Implications for the ProfessionThese findings serve to highlight the key areas for training in PD management and aim to empower patients to effectively conduct self‐management practices.Patient or Public ContributionWe appreciate the patient's understanding and support.

Published: December 2024

AbstractBackgroundParental depression has consistently been shown to impact child's emotion regulation (ER), with limited research on risk and protective factors, especially in preschoolers. Grounded in Morris and colleagues' model of emotion socialization, this study addresses this gap by examining the mediating and moderating roles of parental mentalizing (reflective functioning).AimsWe aimed to explore whether pre‐mentalizing modes mediate the link between parental depressive symptoms and the child's ER tendencies and whether parental interest and curiosity and parental certainty about mental states can buffer this link.Materials & MethodsThe study sample included 732 parents (91% females) of children aged 3–7 years. To assess parental mentalizing, the Parental Reflective Functioning Questionnaire was used. Child ER skills were assessed with the Emotion Regulation Checklist, and depression was assessed with the Patient Health Questionnaire.ResultsFindings demonstrated a negative link between parental depressive symptoms and children's ER skills, mediated by heightened parental pre‐mentalizing modes. Contrary to expectations, parental interest and curiosity did not moderate this link, but parental certainty about mental states emerged as a protective factor, weakening the link between depressive symptoms and child ER skills.ConclusionThe results contribute to the understanding of ER development, particularly in the context of parental depressive symptoms, emphasizing parental mentalizing as a pivotal factor within this intricate dynamic.
Mixing and matching: Intra‐stream interdependence in the multiple streams framework and the adoption of policy mixes
Authors: Soni Anmol , Mistur Evan M. 
Published: December 2024

AbstractPolicy process literature offers several frameworks and theories to understand the adoption or modification of policies across different jurisdictions. Extant studies focus on the emergence of coalitions, actors, strategies, etc. as they relate to individual policies. Policy actions, however, are typically deployed as packages—combinations of different instruments or measures. Policy mixes—also used interchangeably with terms such as policy packaging, policy bundling, etc.—are an important aspect of policy design. However, the role and emergence of policy mixes in the context of the policy process have not been studied in great depth. This study examines the role of different policy pathways that yield desired policy outcomes in the electric vehicle (EV) policy subsystem. We use the case of sub‐national EV policies across the US to analyze how different combinations of policy actions operate in combination and/or competition with each other to achieve the desired policy objectives. The study contributes to the policy design scholarship in two ways. First, by analyzing the emergence of policy mixes as policy outputs during the policy design process using a theoretical lens applying the multiple streams framework. Second, by deploying fuzzy set Qualitative Comparative Analysis as a methodological tool to uncover causal pathways to desired policy outcomes.

AbstractPoor inhibitory control and exaggerated threat reactivity are two well‐established risk factors for suicide. Theory suggests that these two factors may interact to influence suicide risk, although few studies have directly tested these relationships. In the present study, we examined the unique and interactive effects of inhibitory control (IC) and threat reactivity on self‐reported suicide risk in a sample of 132 youth, ages 16–19. The stop signal task was used as a behavioral index of IC. Threat reactivity was captured using a modified version of the No‐Predictable–Unpredictable threat paradigm that includes threat of predictable (P‐) and unpredictable (U‐) mild electrical shock. Startle eyeblink potentiation was measured throughout the task as an index of aversive responding. All participants completed a battery of well‐validated self‐report measures including current suicide risk. Hierarchical linear regression analyses controlling for age and sex revealed no main effects of IC or threat reactivity. However, there was a significant IC by reactivity to uncertain threat (U‐threat) interaction. At lower levels of IC, greater startle reactivity to U‐threat was associated with greater suicide risk. At higher levels of IC, there was no association between reactivity to U‐threat and suicide risk. These results suggest that individual differences in IC and reactivity to U‐threat interact to influence suicide cognitions, shedding light on potential subgroups of individuals who might be at elevated risk.
Covid‐19 pandemic and its impact on capital and output distortions: Evidence from China

Published: December 2024

AbstractBased on Harrold's neutral technological progress production function, this paper studies the impact of Covid‐19 on output distortion and capital mismatch of China's A‐share listed firms in 2006–2022. It also identifies the ‘positive transmission’ and ‘backward forcing’ mechanisms of this impact effect. The empirical results suggest that there existed positive output distortion and negative capital allocation distortion and the pandemic is found to have exacerbated such distortions, especially in the manufacturing and services industries, the central and eastern regions, high‐tech industries and private firms. In the ‘positive transmission’ mechanism, reducing capital cost and improving technological progress are found to have restrained the distortions induced by the pandemic. In the ‘backward forcing’ mechanism, reducing product price is found to have reduced the distortions, but promoting market share competition is only found to have mitigated output distortion. There is heterogeneity in the efficiency of the transmission mechanisms between industries, regions, technological industry and ownership types. This study provides a solid theoretical basis and empirical evidence guiding central and regional authorities on how to alleviate resource allocation distortions and improve firm performance in response to an unexpected external shock such as the Covid‐19 pandemic.

AbstractBurn injuries undergo a complex healing process in which progressive spreading of epithelial damage can lead to secondary complications such as wound infection, which is a major driver of mortality among burn patients. We recently reported that burning larval zebrafish triggers dysregulated keratinocyte dynamics compared to mechanical injury. Here, we investigate keratinocyte behaviour following burn injury and the subsequent potential for microbial colonisation of burn wounds over time. Real‐time imaging, coupled with tracking of photoconverted cells, revealed that early keratinocyte motility contributes to the spread of epithelial damage beyond the initial site of burn injury and that increased epithelial damage was associated with wound colonisation by the fungal pathogen Candida albicans. Modulating osmotic balance by treating larval zebrafish with isotonic medium limited the spread of epithelial damage and reduced microbial colonisation of burn wounds. Using cultured human skin, we found that topical treatment with isotonic solution (saline) similarly prevented the spread of epithelial damage over time. These findings indicate that keratinocyte behaviour contributes to burn wound progression in larval zebrafish and links keratinocyte dynamics to microbial colonisation of burn wounded tissue.
Swirling Flow Effects on the Aeroacoustic Signature of an Aerospike Nozzle
Authors: Golliard Thomas , Mihaescu Mihai 
Published: December 2024

Abstract
Supersonic nozzles are not always operated at design conditions. The total pressure, temperature, and velocity distributions at the nozzle inlet plane are often characterized by inhomogeneities, conditions dictated by the operating regime of the turbine or combustion chamber. In particular, a swirling flow motion can be induced by these components. While homogeneous inflow conditions are well documented for a large range of supersonic nozzles, data on the aeroacoustics of supersonic swirling jets is scarce. Large eddy simulations are deployed to simulate the swirling flow of a nonideally expanded three-dimensional, cold, axisymmetric aerospike nozzle at a nozzle pressure ratio (NPR) of 3. Three swirl numbers are considered and compared with the baseline case. Near-field acoustic analyses are completed by far-field acoustic computations based on the Ffowcs Williams–Hawkings (FWH) equation. Swirling flow shortens the potential core of the jet and leads to an annular shock cell length increase. Two-point space-time cross correlations of pressure data acquired in the annular shear layer indicate an enhancement of the azimuthal modes. Similar cross correlations in the circular jet shear layer further downstream show that screech tones are suppressed. Power spectral density of the radial velocity at monitoring points in the vicinity of the nozzle trailing edge allows to identify the oscillation modes of the annular shock cell structure. The far-field spectra exhibit lower mixing noise with the increasing swirl number. The global sound pressure level (SPL) decreases, while the nozzle thrust remains at 99% of the baseline thrust at low swirl numbers.

Purpose: Bone mineral measurements and their association with peak impact and sport-specific, persistent muscle loads were examined in 10 elite artistic swimmers age 15–19 years. Methods: Bone mineral density (BMD) and bone mineral content (BMC) of total body, total body less head, spine, and dominant and nondominant limbs were assessed by dual-energy X-ray absorptiometry. Peak ground-reaction forces of 2 dry jumps (countermovement jump and frog jump) were measured on a force plate. Peak forces applied during in-water exercises (vertical scull, barracuda push, and kick pull) were measured. Results: On average, artistic swimmers’ total-body BMD (1.12 [0.08] g/cm2) was similar to values reported for young swimmers and nonathletic females, and total-body BMC (2359 [399] g) was higher than previously reported in race swimmers. Based on previously published reference curves, 9 out of 10 artistic swimmers had total-body less head BMD and BMC at or above the 90th percentile, with average to above average z scores and height-adjusted z scores for their age. Countermovement jump and frog jump exhibited moderate peak ground-reaction forces (2.61 [0.46] and 1.93 [0.42] N/kg, respectively). In water, greater force was exerted in kick pull (60.4 [4.8] N) compared with vertical skull (45.5 [6.4] N) and barracuda push (40.6 [4.8] N). Bone measurements were correlated with the peak ground-reaction forces exerted in both dry jumps (r = .61–.83, P ≤ .05) and the peak force output of the in-water exercises (r = .63–.80, P ≤ .05). Conclusion: These results imply robust bone health among artistic swimmers, partially associated with the high muscle forces regularly applied during their sport-specific training that seem to counteract the low-impact nature of the sport.
