Emotion regulation and attachment styles are interrelated and are critical factors in psychopathology and treatment outcomes, particularly in youths with suicidal behavior receiving psychiatric inpatient care. This study examined the influence of emotion regulation and attachment style on psychiatric hospitalization duration among adolescents admitted due to suicidal ideation or behavior. Participants included 79 Israeli adolescents (mean age 15.35 years, 87.3% female) admitted to a tertiary psychiatric inpatient unit following a suicidal crisis. Data was collected using the Difficulties in Emotion Regulation Scale (DERS), the Experience in Close Relationships Scale (ECR), the Screen for Child Anxiety-Related Emotional Disorders (SCARED), the Patient Health Questionnaire (PHQ-9), and the Columbia-Suicide Severity Rating Scale (C-SSRS). Data were analyzed using correlation and multiple regression analyses. Analysis revealed that greater emotion regulation difficulties predicted longer hospitalization duration (β = 0.41, p < 0.001), while avoidant attachment style was associated with shorter hospitalization duration (β = -0.35, p < 0.001). Notably, the level of suicidality as well as psychopathology symptoms (depression and anxiety) did not predict hospitalization duration. These findings underscore the important role of emotion regulation and attachment style in determining treatment duration in suicidal adolescents, beyond the severity of psychopathology and suicidality, suggesting their unique contribution to treatment planning. Clinical interventions targeting emotion regulation and attachment styles could enhance inpatient care effectiveness, offer a more personalized treatment approach and potentially reducing hospitalization duration.

Partition theory holds that ethnic mixing is associated with violence and therefore promotes separation. This article assesses the empirical validity of this logic through a survey in mixed neighborhoods in Israel. The findings largely contrast with partition theory, suggesting that Jewish and Palestinian Israelis interact frequently and positively with each other, and that these interactions are associated with support for contested conflict resolution proposals. Consistent with the psychology literature on inter-group contact, the identified correlations show that even in conflict environments marked by physical separation and violence, ethnic mixing may be related to peaceful interactions and support for conflict resolution.

Subscription-based service model, where profitability arises from sustained service relationships with consumers, has emerged as the dominant business paradigm across various industries. A notable characteristic of the growth in service markets is the indirect relationship between adoption and monetization. While adoption marks the initial stage of user engagement, monetization occurs gradually as users integrate the service into their routines over time. Consequently, the focus has shifted away from emphasizing adoption rates to prioritizing the total number of users . The difference between adopters and users is due to the fact that not all users integrate the service to their routine and some (or many) of them churn away from the service. The growth of adopters and users, and the ensuing monetary growth, are highly affected by churn, hence the critical issue we investigate in this paper is the valence and size effect of churn on adopters, users and revenues of the firm. We build on the service modeling approach of Libai, Muller, and Peres (2009) to first explore the impact of churn on dynamics of growth for new subscription services. We explain how churn affects key interest topics, such as the size and time to peak for adopters and users, the market potential of those who have not adopted yet, adopter categories, and conversion of users to money. We hope this work can motivate further explorations of this critical area for new product research in marketing.

Abstract Transient luminous events (TLEs), such as sprites, have been investigated via observations and simulations for decades. Recent TLE research has focused on effects leading to the delay of a sprite from its parent lightning flash. Here we investigate a sprite with by far the longest recorded delay to date, a delay of almost a full second (916.6 ± 16.6 ms) from the onset of the parent flash, as observed from the ISS during the ILAN‐ES campaign on 6 February 2024. Based on meteorological, satellite, and ground‐based ELF data, we reconstruct a realistic charge configuration for the parent thunderstorm. We input this reconstructed charge configuration to a 3D quasi‐electrostatic model in order to simulate regions of possible sprite inception as a function of time corresponding to this sprite event following the lightning. We demonstrate how the observed delayed sprite could have been incepted by a prolonged piecewise pattern of the current in the parent flash.

The effects of a single stroboscopic training session on anticipating tennis serve direction were explored. Intermediate tennis players in both the stroboscopic training ( n = 16) and control ( n = 16) conditions completed 40 pretest and 40 post-test service video clips, prompting them to indicate the serve trajectory direction. Identical on-court training was provided for both conditions after the pretest, in which each participant was asked to return 40 tennis serve shots. In the experimental condition, participants performed the task wearing stroboscopic glasses, whereas those in the control condition performed the task naturally, without any glasses. Response accuracy and reaction time (RT) were measured. Results revealed that stroboscopic training significantly improved response accuracy. However, there were no significant differences in RT between conditions. The present study indicates that a single training session can improve the anticipation of serve trajectory detection in tennis. Further research must examine the transfer to the natural environment and investigate anticipation in other types of tasks, such as during play in tennis and in other sports.

False or unnecessary Earthquake Early Warning (EEW) alerts risk undermining public trust, potentially leading to alert fatigue or disengagement, a critical concern for policymakers. Although false alerts are inherently unpredictable, a rare opportunity to study one arose on October 26, 2024, when a planned military explosion was mistakenly classified as a magnitude 5.2 earthquake by the Israeli EEW system, triggering alerts to over one million people. This was the first-ever public EEW alert in Israel and occurred during wartime, following a year of near-daily missile alerts. A preregistered survey (N = 1,043) was conducted shortly after this event. Because the alert was geographically limited, the incident offered a quasi-experimental opportunity to compare attitudes between those who received the alert and those who did not. Results showed that the public remained largely motivated to follow EEW guidance and had considerable tolerance for false alerts. However, tolerance was significantly lower for false EEW alerts than false missile alerts, indicating different public perceptions of seismic versus security threats. Despite the false alert and prolonged exposure to alerts, public support for receiving warning, even for non-damaging, felt events, remained strong. These findings highlight the resilience of public trust and offer insights for designing effective alert systems.Supplementary InformationThe online version contains supplementary material available at 10.1038/s41598-026-37958-1.

Ocular manifestations (OMs) are recognized extraintestinal complications in inflammatory bowel disease (IBD), but their incidence remains understudied. We aimed to evaluate the incidence and trends of OM in a large population-based cohort of adults with newly diagnosed IBD over the past 2 decades. We conducted a retrospective cohort study including all adult-onset IBD patients between 2005 and 2024 in a large health maintenance organization. Patients with pre-existing OM diagnoses were excluded. The primary outcome was incident OM (uveitis, episcleritis/scleritis, or orbital inflammation) after IBD diagnosis. Annual incidence trends were assessed using the Cochran-Armitage test. Risk factors were analyzed via multivariable Cox regression, stratified by IBD type. Among 15 035 newly diagnosed IBD patients (51.8% Crohn's disease [CD], 48.2% ulcerative colitis [UC]), 349 developed an OM over 119 669 person-years (incidence: 2.9 per 1000 person-years; 95% confidence interval [CI], 2.62-3.24). OM incidence was higher in CD than UC (log-rank P < .001) and remained stable over time (P = .125). The median time to OM was 45 months. In CD, female sex (hazard ratio [HR], 1.62; 95% CI, 1.24-2.13) and systemic corticosteroid use (HR, 1.62; 95% CI, 1.18-2.22) were significant risk factors. In UC, corticosteroids (HR, 2.17; 95% CI, 1.40-3.37) and intestinal surgery (HR, 3.50; 95% CI, 1.69-7.28) were associated with increased OM risk. OMs in adult-onset IBD are infrequent but clinically relevant, particularly among CD patients and those with markers of severe disease. Clinician awareness and early referral remain essential for prompt diagnosis and management.
