Activation of the mPFC-NAc Pathway Reduces Motor Impulsivity but Does Not Affect Risk-Related Decision-Making in Innately High-Impulsive Male Rats.

Attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD) are characterized by exacerbated motor and risk-related impulsivities, which are associated with decreased cortical activity. In rodents, the medial prefrontal cortex (mPFC) and nucleus accumbens (NAc) have been separately implicated in impulsive behaviors, but studies on the specific role of the mPFC-NAc pathway in these behaviors are limited. Here, we investigated whether heightened impulsive behaviors are associated with reduced mPFC activity in rodents and determined the involvement of the mPFC-NAc pathway in motor and risk-related impulsivities. We used the Roman High- (RHA) and Low-Avoidance (RLA) rat lines, which display divergent phenotypes in impulsivity. To investigate alterations in cortical activity in relation to impulsivity, regional brain glucose metabolism was measured using positron emission tomography and [18F]-fluorodeoxyglucose ([18F]FDG). Using chemogenetics, the activity of the mPFC-NAc pathway was either selectively activated in high-impulsive RHA rats or inhibited in low-impulsive RLA rats, and the effects of these manipulations on motor and risk-related impulsivity were concurrently assessed using the rat gambling task. We showed that basal [18F]FDG uptake was lower in the mPFC and NAc of RHA compared to RLA rats. Activation of the mPFC-NAc pathway in RHA rats reduced motor impulsivity, without affecting risk-related decision-making. Conversely, inhibition of the mPFC-NAc pathway had no effect in RLA rats. Our results suggest that the mPFC-NAc pathway controls motor impulsivity, but has limited involvement in risk-related decision-making in our current model. Our findings suggest that reducing fronto-striatal activity may help attenuate motor impulsivity in patients with impulse control dysregulation.

Understanding Gratification Disorder in Childhood: A Comprehensive Review of Diagnosis, Differential Diagnosis, and Management Approaches.

Gratification disorder (GD) in childhood is characterized by difficulty delaying immediate rewards and controlling impulsive behaviors. This disorder manifests as a persistent struggle to wait for longer-term rewards and a tendency toward impulsive decision-making, which can disrupt academic performance, social interactions, and daily functioning. The relevance of GD is highlighted by its potential to impede the development of crucial skills such as self-control, problem-solving, and social competence. This comprehensive review aims to provide an in-depth understanding of GD by examining its diagnostic criteria, exploring differential diagnoses, and evaluating various management strategies. Key objectives include clarifying the characteristics of GD, distinguishing it from other disorders with overlapping symptoms, and assessing effective interventions, including behavioral therapies, pharmacological options, and educational modifications. The review underscores the importance of accurate diagnosis and tailored interventions for clinicians, educators, and parents, emphasizing the need for a multidisciplinary approach to support affected children. Understanding GD is essential for improving developmental outcomes and ensuring that children receive appropriate support to navigate the challenges associated with the disorder. Continued research and advancements in diagnostic and therapeutic practices are crucial for enhancing the management of GD and fostering better long-term outcomes for affected individuals.

An examination of relationships between transdiagnostic psychological processes and mental health disorders in athletes

IntroductionThe aims of this study were (a) to identify links between transdiagnostic psychological processes and mental health disorder (MHD) symptoms, and (b) to examine differences in MHD and transdiagnostic psychological processes as a function of demographic variables, including, gender, status as an athlete (elite vs. non-elite), number of training sessions per week, previous severe injuries, and use of medical care following severe injuries. MethodsA total of 159 competitive athletes aged between 18 and 40 years old (44 % female; mean age = 24.20 ± 4.88 years) participated in this cross-sectional study. Participants completed a demographic questionnaire along with validated questionnaires evaluating MHD symptoms and transdiagnostic processes including: motivation to practice sport, emotional competencies, self-efficacy, repetitive negative thinking, meta-cognitive beliefs, and impulsive and perfectionist behaviors. ResultsMHD symptoms were positively correlated with controlled forms of motivation, repetitive negative thinking, meta-cognitive beliefs, and impulsive and perfectionistic behaviors; and negatively correlated with emotional competencies and self-efficacy. Gender differences showed that women were more likely to experience MHD, higher levels of repetitive negative thinking, meta-cognitive beliefs, and lower levels of emotional competencies and self-efficacy than men. Finally, elite athletes showed higher personal standards than their non-elite counterparts and those training more than four times per week showed significantly higher perfectionistic behaviors. DiscussionThese results are in line with previous findings in clinical psychology and shed light on the role of transdiagnostic processes and the risk of MHD in a sample of French athletes. Further research on the identification of key risk factors for MHD in competitive athletes is needed.

IMPULSE BUYING AND RETAILER LOYALTY PROGRAMS: ASSESS THE INFLUENCE OF LOYALTY PROGRAMS, REWARDS, AND CUSTOMER INCENTIVES ON IMPULSE BUYING

Comprehending the link between impulse buying and retailer loyalty programs is crucial in retail marketing. These programs, designed to encourage repeat purchases and foster customer loyalty with personalized rewards, profoundly impact impulsive behaviors. This study uses a mixed methods approach to assess the effectiveness of loyalty strategies across diverse consumer demographics. Rewards such as discounts, points, or exclusive access cultivate a sense of belonging and exclusivity, influencing purchasing decisions by triggering immediate incentives and urgency through limited time offers. Emotional and psychological factors drive impulse buying. The expectation of rewards, the excitement of earning points, and the sense of exclusivity all play roles in impulsive purchases. Retailers can capitalize on these motivators by tailoring programs accordingly. Demographic variables such as age, income, and shopping habits influence program effectiveness, with younger consumers typically favoring digital rewards and older consumers showing a preference for traditional discounts. Qualitative research delves into motivations and perceptions, providing rich insights into how loyalty programs influence impulse buying behaviors. This holistic approach offers valuable insights for refining marketing strategies, increasing customer loyalty, and promoting impulse buying through personalized rewards, real-time offers, and gamification.

Inhibition of the P38 MAPK/NLRP3 pathway mitigates cognitive dysfunction and mood alterations in aged mice after abdominal surgery plus sevoflurane

BackgroundCognitive dysfunction, encompassing perioperative psychological distress and cognitive impairment, is a prevalent postoperative complication within the elderly population, and in severe cases, it may lead to dementia. Building upon our prior research that unveiled a connection between postoperative mood fluctuations and cognitive dysfunction with the phosphorylation of P38, this present investigation aims to delve deeper into the involvement of the P38 MAPK/NLRP3 pathway in perioperative neurocognitive disorders (PND) in an abdominal exploratory laparotomy (AEL) aged mice model. MethodsC57BL/6 mice (male, 18-month-old) underwent AEL with 3 % anesthesia. Then, inhibitors targeting P38 MAPK (SB202190, 1 mg/kg) and GSK3β (TWS119, 10 mg/kg) were administered multiple times daily for 7 days post-surgery. The NLRP3-cKO AEL and WT AEL groups only underwent the AEL procedure. Behavioral assessments, including the open field test (OFT), novel object recognition (NOR), force swimming test (FST), and fear conditioning (FC), were initiated on postoperative day 14. Additionally, mice designated for neuroelectrophysiological monitoring had electrodes implanted on day 14 before surgery and underwent novel object recognition while their local field potential (LFP) was concurrently recorded on postoperative day 14. Lastly, after they were euthanasized, pathological analysis and western blot were performed. ResultsSB202190, TWS119, and astrocyte-conditional knockout NLRP3 all ameliorated the cognitive impairment behaviors induced by AEL in mice and increased mean theta power during novel location exploration. However, it is worth noting that SB202190 may exacerbate postoperative depressive and anxiety-like behaviors in mice, while TWS119 may induce impulsive behaviors. ConclusionsOur study suggests that anesthesia and surgical procedures induce alterations in mood and cognition, which may be intricately linked to the P38 MAPK/NLRP3 pathway.

Unveiling the optimal configuration of impulsive buying behavior using fuzzy set qualitative comparative analysis and multi-criteria decision approach

Sudden and unplanned purchasing behavior is considered impulsive buying behavior. With the increasing popularity of social commerce platforms and shopping automation, people's tendency towards impulsive purchases has grown significantly. In this connection, the role of marketing influencers has crucially impacted the customers' purchasing decisions over the last decade. This study aims to investigate the effect of marketing influencers on impulsive buying behavior. In addition, the current study addresses a critical methodological problem by highlighting the optimal configuration provided by fuzzy set qualitative comparative analysis (fsQCA) using a multi-criteria decision approach (MCDM). Based on a survey of 672 users of live streaming commerce platforms in Malaysia, we examined impulsive buying behavior from the perspective of influencer marketing, cognitive trust, and affective trust in influencer. Partial Least Squares Structural Equation Modeling (PLS-SEM) results confirmed the influence of parasocial relationship, authenticity, expertise, trustworthiness, attractiveness, and influencer–follower congruence on impulsive buying behavior through cognitive trust in influencer, affective trust in influencer, and behavioral inertia. The fsQCA results provided 15 different configurations confirming the role of marketing influencers' characteristics in impulsive buying behavior. However, fsQCA analysis is unable to determine the optimal solution or configuration. To this end, the MCDM analysis complemented the fsQCA analysis by unveiling the optimal configuration, which was the ninth configuration. Furthermore, the combination of authenticity, expertise, trustworthiness, cognitive trust, affective trust is considered a key concept to increase impulsive buying behaviour regardless of the presence of a parasocial relationship.

Psychometric Properties and Normative Data of the Spanish UPPS-P Impulsive Behavior Scale in Adolescents

Impulsivity is a multidimensional construct linked to a broad spectrum of psychopathological and neuropsychological disorders. The UPPS-P model has emerged as a valuable tool for assessing impulsivity from a multi-dimensional perspective. Despite its relevance, few studies have examined the psychometric properties of the UPPS-P scale scores in a large, representative sample of adolescents. This study aims to evaluate the psychometric properties of the Spanish UPPS-P in adolescents and to establish normative data for this population in Spain. To this end, 9024 students aged 11-19 from 66 different Spanish high schools were included. The fit for the expected 5-factor model, assessed through confirmatory factor analysis, was inadequate (CFI and TLI ≤ .85, RMSEA = .063), but becomes satisfactory when employing the more flexible ESEM approach (CFI and TLI ≥ .94, RMSEA = .038), which was invariant across gender and age. Internal consistency reliability was satisfactory (ω = .83 to .94). Convergent validity with the Barratt Impulsiveness Scale-11-A total score was good (r = .53 to .60). We provide population norms of the UPPS-P, which may help practitioners to interpret the UPPS-P scores of adolescents from the general population in Spain. Subsequent research should explore implications for both clinical and non-clinical settings.

What Emotion Regulation Strategies are Associated with a General Psychopathology Factor (p) in Adolescence? Identifying Possible Transdiagnostic Targets for Intervention.

Mental health problems in adolescence are increasing and there is an urgent call for transdiagnostic interventions, as most adolescents experience problems across multiple domains. Research has identified a general psychopathology factor (p) capturing the shared variance across mental health problems. In parallel, there is empirical support for the transdiagnostic nature of emotion regulation. In the current study, we explore the associations between p and emotion regulation strategies to identify which strategies may be promising targets for intervention. Data from the population-based Youth and Mental Health Study (YAMHS) (N = 2,464, mean age 13.7years, SD 0.6) was used. The fit of different structural models of emotion regulation and psychopathology were compared, and latent factors from the final models were included in multiple regression analyses to explore the associations between p and emotion regulation strategies. A bifactor exploratory structural equation model (B-ESEM) showed best fit for modelling p. For emotion regulation strategies, an ESEM model showed best fit, including Rumination, Reactive Impulsivity, Distraction, Non-Acceptance, Problem Solving, Social Support, and Proactive Behavior. Results showed that a higher score on p was predicted by higher scores on the emotion regulation strategies Rumination (β = .38, p < .001) and Reactive Impulsivity (β = .35, p < .001), and lower scores on Problem Solving (β = -.15, p < .001). The results indicate that Rumination and Reactive Impulsivity have the strongest associations with p and may be promising targets for mental health interventions for adolescents.

Computational Analysis and Experimental Data Exploring the Role of Hesperetin in Ameliorating ADHD and SIRT1/Nrf2/Keap1/OH-1 Signaling.

Attention deficit hyperactivity disorder (ADHD) manifests as poor attention, hyperactivity, as well as impulsive behaviors. Hesperetin (HSP) is a citrus flavanone with strong antioxidant and anti-inflammatory activities. The present study aimed to test hesperetin efficacy in alleviating experimental ADHD in mice and its influence on hippocampal neuron integrity and sirtuin 1 (SIRT1) signaling. An in silico study was performed to test the related proteins. Groups of mice were assigned as control, ADHD model, ADHD/HSP (25 mg/kg), and ADHD/HSP (50 mg/kg). ADHD was induced by feeding with monosodium glutamate (0.4 g/kg, for 8 weeks) and assessed by measuring the motor and attentive behaviors (open filed test, Y-maze test, and marble burying test), histopathological examination of the whole brain tissues, and estimation of inflammatory markers. The in-silico results indicated the putative effects of hesperetin on ADHD by allowing the integration and analysis of large-scale genomic, transcriptomic, and proteomic data. The in vivo results showed that ADHD model mice displayed motor hyperactivity and poor attention in the behavioral tasks and shrank neurons at various hippocampal regions. Further, there was a decline in the mRNA expression and protein levels for SIRT1, the erythroid 2-related factor-2 (Nrf2), kelch like ECH associated protein 1 (Keap1) and hemeoxygenase-1 (OH-1) proteins. Treatment with HSP normalized the motor and attentive behaviors, prevented hippocampal neuron shrinkage, and upregulated SIRT1/Nrf2/Keap1/OH-1 proteins. Taken together, HSP mainly acts by its antioxidant potential. However, therapeutic interventions with hesperetin or a hesperetin-rich diet can be suggested as a complementary treatment in ADHD patients but cannot be suggested as an ADHD treatment per se as it is a heterogeneous and complex disease.

Pengaruh Flash Sale dan Diskon terhadap Impulsive Buying pada Produk Fashion di Shopee

This study aims to measure the extent to which flash sales and discount offers influence impulsive buying decisions. Data were collected through an online survey involving 130 respondents and analyzed using quantitative descriptive methods and Structural Equation Modeling - Partial Least Squares (SEM-PLS) to evaluate the significant effect of flash sales and discounts on impulsive buying. The results showed that marketing strategies involving flash sales and discounts significantly stimulated quick and spontaneous purchasing decisions. This finding highlights the effectiveness of these marketing techniques in increasing consumer impulsive behavior in the fashion category. Keywords: Discount, Flash Sale, Impulsive Buying

Role of Impulsivity in Explaining Social Gradient in Youth Tobacco Use Initiation: Does Race Matter?

Socioeconomic status (SES) is traditionally viewed as a protective factor against impulsivity and subsequent tobacco use in youth. The prevailing model suggests that higher SES is associated with lower impulsivity, which in turn reduces the likelihood of future tobacco use. However, this pathway may not hold uniformly across racial groups due to differences in impulsivity and the phenomenon of Minorities' Diminished Returns (MDRs), where the protective effects of SES, such as educational attainment, tend to be weaker or even reversed for Black youth compared to their White counterparts. This study aims to examine the racial heterogeneity in the pathway from childhood SES to impulsivity and subsequent tobacco use initiation during adolescence, focusing on differences between Black and White youth. Data were drawn from the Adolescent Brain Cognitive Development (ABCD) Study, which includes a diverse sample of youth aged 9 to 16 years. The analysis examined the relationship between baseline family SES (age 9), impulsivity (age 9), and subsequent tobacco use (ages 9 to 16). Impulsivity was measured using the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, and Positive Urgency Impulsive Behavior Scale (UPPS-P). Structural equation modeling (SEM) was employed, with analyses stratified by race to explore potential differences in these associations. Overall, 6,161 non-Latino White and 1,775 non-Latino Black adolescents entered our analysis. In the full sample, higher family SES was linked to lower childhood impulsivity and, consequently, less tobacco uses in adolescence. However, racial differences emerged upon stratification. Among White youth, higher SES was associated with lower impulsivity, leading to reduced tobacco use, consistent with the expected model. In contrast, among Black youth, higher SES was not associated with lower impulsivity, thereby disrupting the protective effect of SES on tobacco use through this pathway. These findings suggest that racial heterogeneity exists in the SES-impulsivity-tobacco use pathway, aligning with the MDRs framework, which highlights how structural factors may weaken the protective effects of high SES among Black youth. These findings underscore the importance of considering racial heterogeneity in the relationships between SES, impulsivity, and tobacco use. The observed disparities suggest a need for targeted interventions that address the unique challenges faced by Black youth, who may not experience the same protective benefits of high SES as their White peers. These results carry significant implications for public health strategies aimed at reducing tobacco use in racially diverse populations.

Cognitive Emotion Regulation Styles and the Impulsive Behavior of Patients with Substance Use Disorders: A Cross-Sectional Study

Cognitive Emotion Regulation Styles and the Impulsive Behavior of Patients with Substance Use Disorders: A Cross-Sectional Study

Longitudinal characterization of impulsivity phenotypes boosts signal for genomic correlates and heritability.

Genomic correlates of impulsivity have been identified in several genome-wide association studies (GWAS) using cross-sectional designs, but no studies have investigated the molecular genetic correlates of impulsivity phenotypes using longitudinally constructed traits. In 3860 unrelated European participants in the Avon Longitudinal Study of Parents and Children (ALSPAC), we constructed longitudinal phenotypes for delay discounting and impulsive personality traits (as measured by the UPPS-P impulsive behavior scales) via assessment at ages 24, 26, and 28. We conducted GWASs of impulsivity using both cross-sectional and longitudinal phenotypes, estimated heritability and their phenotypic and genetic correlations, and evaluated their association with recently-developed polygenic risk scores (PRSs) for the impulsivity indicators themselves and also related psychiatric conditions. Latent growth curve modeling revealed a stable intercept over time for all impulsivity phenotypes. High genetic correlation of cross-sectional measures over time suggested a stable genetic component for delay discounting (rg = 0.53-0.99) and sensation seeking (rg = 0.99). Heritability estimates of the stable longitudinal phenotypes substantively improved as compared to their cross-sectional counterparts, revealing a significant SNP-heritability for delay discounting (0.22; p = 0.03) and sensation seeking (0.35; p = 0.0007). Consistent with previous reports, GWAS and gene-based analyses revealed associations between specific longitudinal impulsivity indicators and CADM2 and NCAM1 genes. The PRSs for the impulsivity indicators and disorders related to self-regulation were also significantly associated with longitudinal impulsivity traits. Finally, we validated the associations between longitudinal impulsivity phenotypes and their PRSs in an independent 13-wave longitudinal study (n = 1019) and the benefit of longitudinal phenotypes in simulation studies. In this first longitudinal genetic study of impulsivity traits, the results revealed stable genomic correlates of delay discounting and sensation seeking over time and further validated the utility of recently-developed PRSs, both in relation to the observed traits and in connecting them to psychiatric disorders. More generally, these findings support using latent intercepts as novel longitudinal phenotypes to boost signal for heritability and genomic correlates of mechanisms contributing to psychiatric disease liability.

Examining change in the mental health of young people with epilepsy following a successful psychological intervention.

Evaluate the cognitive, behavioural and affective processes involved in therapeutic change for young people with epilepsy and mental health difficulties receiving an integrated mental health intervention. As part of a mixed methods convergent design, qualitative data were gathered in parallel to quantitative data at two timepoints in a randomised controlled trial testing the Mental Health Intervention for Children with Epilepsy in addition to usual care. Twenty-five young people and/or their families were interviewed before and after the intervention about the young person's mental and physical health, and their experience of therapy. Interview data were analysed inductively, idiographically and longitudinally using Interpretative Phenomenological Analysis combined with Framework Analysis. The young people's emotional and behaviour problems improved, mirroring the trial's quantitative outcomes. Their anxiety decreased and behaviour improved as they acquired tools and understanding through therapy. Problems, like aggressive behaviours and emotional outbursts, were also reduced, with young people gaining increased awareness and ability to self-regulate and parents learning to contain their child's impulsive behaviours. The qualitative findings complement the MICE trial's significant positive quantitative results by providing insight and context to the therapeutic change, providing vivid insight into the mechanisms of therapy for individual families.

Efficacy of Transcranial Direct Current Stimulation on the Dorsolateral Prefrontal Cortex in Reducing Craving, Depression, and Improving Working Memory in Patients with Cannabis Use Disorders: A Randomized, Double-blind, Sham-controlled

Background: The beneficial effect of transcranial direct current stimulation (tDCS) on substance use disorders, achieved by reducing craving, impulsivity, and risk-taking behavior, can be considered an effective therapeutic approach. Transcranial direct current stimulation can be considered an effective therapeutic approach for reducing cannabis craving, improving levels of depression, and enhancing working memory in cannabis users. Objectives: This study investigated the effectiveness of tDCS applied to the Dorsolateral prefrontal cortex (DLPFC) on craving, depression, and working memory in cannabis users. Methods: This was a randomized, sham-controlled, double-blind, parallel-group study. Fifty male participants who met the criteria for cannabis use disorder according to DSM-5 were randomly assigned to either the real tDCS group (25 participants) or the sham tDCS group (25 participants). Pretests, including marijuana urine tests, the Marijuana Craving Questionnaire-Short Form (MCQ-SF), the Hamilton Depression Rating Scale (HDRS), and the Wechsler Memory Scale, were conducted before the intervention. The real tDCS group underwent 20 sessions of tDCS stimulation, each lasting 20 minutes, with a current intensity of 2 milliamperes applied at the F3 and F4 positions for DLPFC stimulation. The sham tDCS group received only 30 seconds of initial electrical stimulation, with no further current delivered. Both groups also received standard psychological treatments alongside the tDCS interventions. After completing the interventions, the same tests were administered again to assess the outcomes. Results: Participants who received real tDCS showed significant improvement in levels of craving, depression, and working memory. This reduction in scores and levels was statistically significant compared to the sham group. Conclusions: Transcranial direct current stimulation can be considered an effective therapeutic approach for reducing cannabis craving, improving levels of depression, and enhancing working memory in cannabis users.

Basal forebrain-lateral habenula inputs and control of impulsive behavior.

Deficits in impulse control are observed in several neurocognitive disorders, including attention deficit hyperactivity (ADHD), substance use disorders (SUDs), and those following traumatic brain injury (TBI). Understanding brain circuits and mechanisms contributing to impulsive behavior may aid in identifying therapeutic interventions. We previously reported that intact lateral habenula (LHb) function is necessary to limit impulsivity defined by impaired response inhibition in rats. Here, we examine the involvement of a synaptic input to the LHb on response inhibition using cellular, circuit, and behavioral approaches. Retrograde fluorogold tracing identified basal forebrain (BF) inputs to LHb, primarily arising from ventral pallidum and nucleus accumbens shell (VP/NAcs). Glutamic acid decarboxylase and cannabinoid CB1 receptor (CB1R) mRNAs colocalized with fluorogold, suggesting a cannabinoid modulated GABAergic pathway. Optogenetic activation of these axons strongly inhibited LHb neuron action potentials and GABA release was tonically suppressed by an endogenous cannabinoid in vitro. Behavioral experiments showed that response inhibition during signaled reward omission was impaired when VP/NAcs inputs to LHb were optogenetically stimulated, whereas inhibition of this pathway did not alter LHb control of impulsivity. Systemic injection with the psychotropic phytocannabinoid, Δ9-tetrahydrocannabinol (Δ9-THC), also increased impulsivity in male, and not female rats, and this was blocked by LHb CB1R antagonism. However, as optogenetic VP/NAcs pathway inhibition did not alter impulse control, we conclude that the pro-impulsive effects of Δ9-THC likely do not occur via inhibition of this afferent. These results identify an inhibitory LHb afferent that is controlled by CB1Rs that can regulate impulsive behavior.

The Influence of Cecal Microbiota Transplantation on Chicken Injurious Behavior: Perspective in Human Neuropsychiatric Research.

Numerous studies have evidenced that neuropsychiatric disorders (mental illness and emotional disturbances) with aggression (or violence) pose a significant challenge to public health and contribute to a substantial economic burden worldwide. Especially, social disorganization (or social inequality) associated with childhood adversity has long-lasting effects on mental health, increasing the risk of developing neuropsychiatric disorders. Intestinal bacteria, functionally as an endocrine organ and a second brain, release various immunomodulators and bioactive compounds directly or indirectly regulating a host's physiological and behavioral homeostasis. Under various social challenges, stress-induced dysbiosis increases gut permeability causes serial reactions: releasing neurotoxic compounds, leading to neuroinflammation and neuronal injury, and eventually neuropsychiatric disorders associated with aggressive, violent, or impulsive behavior in humans and various animals via a complex bidirectional communication of the microbiota-gut-brain (MGB) axis. The dysregulation of the MGB axis has also been recognized as one of the reasons for the prevalence of social stress-induced injurious behaviors (feather pecking, aggression, and cannibalistic pecking) in chickens. However, existing knowledge of preventing and treating these disorders in both humans and chickens is not well understood. In previous studies, we developed a non-mammal model in an abnormal behavioral investigation by rationalizing the effects of gut microbiota on injurious behaviors in chickens. Based on our earlier success, the perspective article outlines the possibility of reducing stress-induced injurious behaviors in chickens through modifying gut microbiota via cecal microbiota transplantation, with the potential for providing a biotherapeutic rationale for preventing injurious behaviors among individuals with mental disorders via restoring gut microbiota diversity and function.

The Effect of Attractiveness, Expertise, Visual Attractiveness and Interactivity on Online Impulsive Buying Behavior

An innovative approach to product marketing through live streaming on TikTok can potentially encourage impulsive buying behavior among Indonesian customers, offering opportunities for e-commerce business owners to increase sales. This research focuses on identifying factors influencing impulsive purchasing decisions for fashion products through live streaming on TikTok, namely attractiveness, expertise, visual appeal, and interactivity. Using the Stimulus-Organism-Response (SOR) theoretical framework, this study explores consumer reactions and behaviors caused by stimulus factors which are then analyzed using Structural Equation Modeling (SEM) PLS techniques with the SmartPLS application based on 156 valid respondents on TikTok. The results are expected to guide fashion business actors in social commerce to design effective marketing strategies using TikTok live streaming by emphasizing aspects of perceived enjoyment to encourage impulse buying.

Video Game Addiction in Young People (8-18 Years Old) after the COVID-19 Pandemic: The Grey Area of Addiction and the Phenomenon of "Gaming Non-Pathological Abuse (GNPA)".

In the literature, video game addiction in youths is correlated with dysfunctional symptoms of anxiety, emotional disorders, and mood disorders, and the pandemic period of 2020-2022 has favored the aggravation of this behavioral addiction. Therefore, we identified the need to analyze this phenomenon with an emphasis on the risks and correlates related to deviance and maladjustment from a prospective perspective, seeking to understand the impact of the individual variables examined. To demonstrate whether the condition of "gaming non-pathological abuse" (GNPA) promotes psychopathological features of clinical interest, in the absence of a diagnosis of "gaming disorder" (GD). A search performed on PubMed and administration of an ad hoc sociological questionnaire were used to investigate individual variables of criminological interest in a representative population sample (531 males/females, 8-18 years old, M: 14.4, SD: 2.5). Statistical analysis showed that after the pandemic period, digital video game addiction was reinforced, feeding psychopathological traits consistent with anxiety, emotional disorders, and mood disorders. Variables correlated with impulsive, aggressive, and violent behavior related to age, gender, socio-environmental and economic background, and the severity of digital video game addiction. In the youth population (8-18 years), "gaming non-pathological abuse" (GNPA) is related to aggressive, impulsive and violent behaviors that foster phenomena of social maladjustment and deviance, especially in individuals living in disadvantaged or otherwise complex socio-economic and family contexts. Looking forward, the study of structural and functional personality profiles is essential in order to anticipate and reduce the future risk of psychopathological and criminal behavior.

Robust variance estimators in application to segmentation of measurement data distorted by impulsive and non-Gaussian noise

The paper algorithmizes the problem of regime change point identification for data measured in a system exhibiting impulsive behaviors. This is a fundamental challenge for annotation of measurement data, relevant, e.g., for designing data-driven autonomous systems. The contribution consists in formulation of an offline robust methodology based on the classical approach for structural break detection. The problem of data segmentation for the changing scale is solved as a process variable sensitive to the occurrence of a critical event in a reorganizing physical system. The advantage is that this approach does not require the existence of a variance of the data distribution. Efficiency has been evaluated for simulated data from two distributions and for real-world data sets measured in financial, mechanical, and medical systems. Simulation studies show that in the most challenging case, the error mean absolute in estimating the regime change is 20 times lower for the robust approach compared to the classical approach.
