RESUMEN
Graphs are data structures that effectively represent relational data in the real world. Graph representation learning is a significant task since it could facilitate various downstream tasks, such as node classification, link prediction, etc. Graph representation learning aims to map graph entities to low-dimensional vectors while preserving graph structure and entity relationships. Over the decades, many models have been proposed for graph representation learning. This paper aims to show a comprehensive picture of graph representation learning models, including traditional and state-of-the-art models on various graphs in different geometric spaces. First, we begin with five types of graph embedding models: graph kernels, matrix factorization models, shallow models, deep-learning models, and non-Euclidean models. In addition, we also discuss graph transformer models and Gaussian embedding models. Second, we present practical applications of graph embedding models, from constructing graphs for specific domains to applying models to solve tasks. Finally, we discuss challenges for existing models and future research directions in detail. As a result, this paper provides a structured overview of the diversity of graph embedding models.
RESUMEN
Violence experience has been consistently associated with HIV risks and substance use behaviors. Although many studies have focused on intimate partner violence (IPV), the role of violence at a structural level (i.e., police abuse) remains relevant for people who inject drugs. This study evaluated the association of IPV and police-perpetrated violence experiences with HIV risk behaviors and substance use in a cohort of HIV-positive people who inject drugs in Ukraine. We also evaluated possible moderation effects of gender and socioeconomic status in the links between violence exposure and HIV risk and polysubstance use behaviors. Data came from the Providence/Boston-CFAR-Ukraine Study involving 191 HIV-positive people who inject drugs conducted at seven addiction treatment facilities in Ukraine. Results from logistic regressions suggest that people who inject drugs and experienced IPV had higher odds of polysubstance use than those who did not experience IPV. Verbal violence and sexual violence perpetrated by police were associated with increased odds of inconsistent condom use. The odds of engaging in polysubstance use were lower for women in relation to police physical abuse. We found no evidence supporting socioeconomic status moderations. Violence experiences were associated with substance use and sexual HIV risk behaviors in this cohort of HIV-positive people who inject drugs in Ukraine. Trauma-informed prevention approaches that consider both individual and structural violence could improve this population's HIV risks.
RESUMEN: La experiencia de violencia se ha asociado sistemáticamente con las conductas de riesgo para la adquisición o transmisión del VIH y con el uso de sustancias. Aunque muchos estudios se han centrado en la violencia infligida por la pareja íntima (VPI), el papel de la violencia estructural (es decir, el abuso policial) sigue siendo relevante para las personas que se inyectan drogas. Este estudio evaluó la asociación entre las experiencias de violencia perpetrada por la policía y la pareja íntima con los conductas de riesgo para la adquisición o transmisión del VIH y el uso de sustancias en una cohorte de personas VIH positivas que se inyectan drogas en Ucrania. También evaluamos los posibles efectos de moderación del género y el estatus socioeconómico entre la exposición a la violencia y los comportamientos de riesgo para la transmisión del VIH y uso de múltiples sustancias. Los datos provienen del estudio Providence / Boston-CFAR-Ucrania en el que participaron 191 personas infectadas por el VIH que se inyectan drogas, realizado en siete centros de tratamiento de adicciones en Ucrania. Los resultados de las regresiones logísticas sugieren que, en comparación con las personas que se inyectan drogas que no experimentaron IPV, las que experimentaron IPV tenían mayor probabilidad de uso de múltiples sustancias. La violencia sexual perpetrada por la policía se asoció con mayores probabilidades de un uso inconsistente del condón. No encontramos evidencia que apoye las moderaciones de género o estatus socioeconómico. Las experiencias de violencia se asociaron con el uso de sustancias y las conductas sexuales de riesgo para la transmisión del VIH en esta cohorte de personas VIH positivas que se inyectan drogas en Ucrania. Los enfoques de prevención basados en las experiencias traumáticas que tienen en cuenta tanto la violencia individual como la estructural podrían mejorar las conductas de riesgo para la transmission del VIH de esta población.

Young adulthood represents a developmental period with disproportionately heightened risk of losing a job. Young adult unemployment has been linked to increased mental health problems, at least in the short term. However, their possible long-term impacts, often referred as "scarring effects," have been understudied, possibly underestimating the magnitude of mental health burden that young adult unemployment generates. This longitudinal study examined whether duration of unemployment during young adulthood is associated with later mental health disorders, after accounting for mental and behavioral health problems in childhood. Furthermore, the current study investigated whether childhood neighborhood characteristics affect this association and if so, in what specific functional ways. Data were drawn from a longitudinal study of developmental outcomes in a community sample in Seattle. Data collection began in 1985 when study participants were elementary students and involved yearly assessments in childhood and adolescence (ages 10-16) and then biennial or triennial assessments (ages 18-39; N = 677 at age 39; 47% European American, 26% African American, 22% Asian American, and 5% Native American; 49% female). The current study findings suggest that duration of unemployment across young adulthood increased mental health problems at age 39, regardless of gender. Childhood neighborhood characteristics, particularly their positive aspect, exerted independent impacts on adult mental health problems beyond unemployment experiences across young adulthood. The current findings indicate a needed shift in service profiles for unemployed young adults-a comprehensive approach that not only facilitates reemployment but also addresses mental health needs to help them to cope with job loss. Further, the present study findings suggest that childhood neighborhoods, particularly positive features such as positive neighborhood involvement, may represent concrete and malleable prevention targets that can curb mental health problems early in life.

INTRODUCTION: The present study aims to investigate whether problem-focused and emotion-focused coping skills were associated with suicidal ideation. In addition, we examined whether childhood maltreatment (i.e. physical, psychological, sexual abuse, and neglect) is a risk factor for later-on suicidal ideation. METHODS: Youths aged 16 or 18 (nâ¯=â¯307, 56% females) from San Diego and Seattle at Wave 6 and Wave 7 of the LONGSCAN were included in the study. We used hierarchical logistic regression. RESULTS & CONCLUSIONS: 17.6% reported suicidal ideation. Those who reported better emotion-focused coping were .80 times less likely to report suicidal ideation. However, even after controlling for coping skills, adolescents with sexually abuse histories were 3.08 times more likely to report suicidal ideation. Our findings suggest implications for early intervention efforts. Building youth assets through promotion of positive youth development may serve as a driving force to reduce negative outcomes in youth who have experienced sexual abuse.

Although lower socioeconomic status has been linked to increased youth substance use, much less research has determined potential mechanisms explaining the association. The current longitudinal study tested whether alternative (i.e., pleasure gained from activities without any concurrent use of substances) and complementary (i.e., pleasure gained from activities in tandem with substance use) reinforcement mediate the link between lower socioeconomic status and youth substance use. Further, we tested whether alternative and complementary reinforcement and youth substance use gradually unfold over time and then intersect with one another in a cascading manner. Potential sex differences are also examined. Data were drawn from a longitudinal survey of substance use and mental health among high school students in Los Angeles. Data collection involved four semiannual assessment waves beginning in fall 2013 (N = 3395; M baseline age = 14.1; 47% Hispanic, 16.2% Asian, 16.1% multiethnic, 15.7% White, and 5% Black; 53.4% female). The results from a negative binomial path model suggested that lower parental socioeconomic status (i.e., lower parental education) was significantly related to an increased number of substances used by youth. The final path model revealed that the inverse association was statistically mediated by adolescents' diminished engagement in pleasurable substance-free activities (i.e., alternative reinforcers) and elevated engagement in pleasurable activities paired with substance use (i.e., complementary reinforcers). The direct effect of lower parental education on adolescent substance use was not statistically significant after accounting for the hypothesized mediating mechanisms. No sex differences were detected. Increasing access to and engagement in pleasant activities of high quality that do not need a reinforcement enhancer, such as substances, may be useful in interrupting the link between lower parental socioeconomic status and youth substance use.

BACKGROUND: Korea is known for its technological prowess, has the highest smartphone ownership rate in the world at 95%, and the smallest gap in smartphone ownership between generations. Since the onset of the COVID-19 pandemic, problematic smartphone use is becoming more prevalent among Korean children and adolescent owing to limited school attendance and outdoor activities, resulting in increased reliance on smartphones. 40.1% of adolescents are classified as high-risk, with only the adolescent group showing a persistent rise year after year. OBJECTIVE: The study purpose is to present data-driven analysis results for predicting and preventing smartphone addiction in Korea, where problematic smartphone use is severe. PARTICIPANTS AND METHODS: To predict the risk of problematic smartphone use in Korean children and adolescents at an early stage, we used data collected from the Smartphone Overdependence Survey conducted by the National Information Society Agency between 2017 and 2021. Eight representative machine and deep learning algorithms were used to predict groups at high risk for smartphone addiction: Logistic Regression, Random Forest, Gradient Boosting Machine (GBM), extreme Gradient Boosting (XGBoost), Light GBM, Categorical Boosting, Multilayer Perceptron, and Convolutional Neural Network. RESULTS: The XGBoost ensemble algorithm predicted 87.60% of participants at risk of future problematic smartphone usebased on precision. Our results showed that prolonged use of games, webtoons/web novels, and e-books, which have not been found in previous studies, further increased the risk of problematic smartphone use. CONCLUSIONS: Artificial intelligence algorithms have potential predictive and explanatory capabilities for identifying early signs of problematic smartphone use in adolescents and young children. We recommend that a variety of healthy, beneficial, and face-to-face activities be offered as alternatives to smartphones for leisure and play culture.

The present study investigates how parenting stress mediates the intergenerational continuity of childhood adversity in teenage mothers. Childhood adversity experiences of caregivers significantly affect their offspring's exposure to childhood adversity. However, little is known about the mechanisms linking childhood adversity across generations. The study measures how parental distress and parent-child dysfunctional interaction mediate the association between teen mothers' childhood adversity and their offspring's adversity, measuring when the offspring reached 11.5 years of age. The results revealed that parental distress, but not parent-child dysfunctional interaction, mediated the association between teen mothers' child abuse and their offspring's household dysfunction. This suggests that parental distress may be a crucial intervention target to prevent the intergenerational continuity of childhood adversity. The findings imply that efforts to prevent the intergenerational continuity of childhood adversity may be more successful if the public and professionals have a broader understanding of the associations between early adversity and parenting contexts. In conclusion, the study shed light on the potential mechanisms underlying the intergenerational continuity of childhood adversity and highlights the importance of targeting parenting stress, specifically parental distress, as an intervention strategy to prevent the perpetuation of childhood adversity across generations.
RESUMEN
Childhood adversities are associated with compromised behavioral health later in life. However, less attention has been paid to how time contributes to the damaging effects of adversity exposure. In addition, the differential impact of childhood maltreatment and household dysfunction has been understudied. The current study tested (a) the sensitive period hypothesis regarding timing of childhood adversity on externalizing behavior, (b) the accumulation hypothesis regarding the associations between the duration of childhood adversity and externalizing behavior, and (c) the domain-specific impact of childhood adversity on externalizing behavior. Data came from the Young Women and Child Development Study (N = 240). Childhood adversity was measured at seven periods (age range: 5.5-16), which were used to test the sensitive period hypothesis. Childhood adversity at each time period was summed across seven time periods to test the accumulation measure representing the duration of childhood adversity. Least angle and multiple regression analyses were conducted. Results supported the sensitive period hypothesis-the effect of childhood adversity was the most prominent at age 11.5, whereas the accumulation of childhood adversity time periods was not a significant predictor of later externalizing behavior. Probing childhood adversity by subdomains revealed maltreatment primarily accounted for externalizing behavior (p < .05). Findings suggest intervention efforts for children of teen mothers during early adolescence to prevent externalizing behavior in later adolescence. Unpacking childhood adversity may illuminate key areas of vulnerability to externalizing behavior.

The main purpose of this study was to examine the association of family polyvictimization in childhood with the victimization or perpetration of spousal abuse and the perpetration of child abuse in adulthood. While associations between maltreatment in childhood and subsequent perpetration or victimization in adulthood are well documented, their association with polyvictimization in childhood (i.e., experiencing multiple types of victimization) has received less attention. This research aims to empirically investigate 1) whether early experiences of family polyvictimization are predictive of subsequent experience or spousal abuse or perpetration of child abuse and 2) whether there are gender differences in those associations. Through conducting Chi-square analysis and logistic regression analysis with South Korea's National Domestic Violence Survey 2019, the study found significant empirical evidence that polyvictimization is predictive of perpetration or experience of spousal abuse and perpetration of child abuse. Particularly, adults who experienced polyvictimization in childhood were more likely to perpetrate child abuse regardless of the type of abuse (p < .001). Polyvictimization in childhood was also significantly associated with perpetration and victimization of spousal abuse (p < .001). In regard to gender differences, this study found that males were more likely to be polyvictimized by family in childhood (15.11%) than females (10.23%), and polyvictimization was found to increase the likelihood of females being revictimized in adulthood. More attention should be paid to victimization by multiple types of violence within the family and its influence on intergenerational transmission of violence.

PURPOSE: Rapid repeat pregnancy is associated with negative outcomes for teen mothers and their offspring. Contraceptive use can reduce this risk. We explored the impact of AIM for Teen Moms, a future-oriented behavioral intervention, on emotional and tangible support and the influence of this support on the attitudes, intentions, and past 3-month contraceptive use behaviors. METHOD: Participants were 295 first-time moms (ages 15-19) in Los Angeles County who participated in a randomized control trial intervention to reduce rapid repeat pregnancies. Participants completed surveys at baseline and 36-months. Hypotheses were tested using multivariate and interaction analysis. RESULTS: Teen mothers in treatment group reported more emotional (ß =.13, p < .05) and tangible support (ß =.13, p < .05). Higher tangible support was positively associated with birth control attitudes (ß =.13, p < .05), which, in turn, predicted intention to use birth control (ß =.31, p < .001). Intention to use birth control also predicted higher past 3-month birth control use (ß =.18, p < .01); there was also a direct path from attitude to 3-month birth control use (ß =.35, p < .001). There was no association between emotional support and birth control attitudes, intentions, or behaviors. CONCLUSION: AIM for Teen Mom's effects on contraception use at 36 months was mediated by social support, specifically tangible support, which, in turn, affected birth control attitudes, intentions, and reported birth control use. Interventionists must consider how intervention content can specifically address the building of target support to meet the needs of teen mothers.

PURPOSE: Adolescent involvement in cyberbullying is common and involves several roles (witness, perpetrator, or victim). Whether different cyberbullying roles are differentially associated with substance use is unknown. The present study examined the associations of adolescent cyberbullying involvement with use and polyuse of various substances. METHODS: A longitudinal cohort of students in Los Angeles, California (N = 2,768) completed surveys at baseline (10th grade, 2014, mean age = 15.5 years) and 12-month follow-up (11th grade, 2015). Five mutually exclusive cyberbullying roles were identified at baseline-no involvement; witness only; witness and victim; witness and perpetrator; and witness, victim, and perpetrator. Past 6-month use of nine substances and poly-use of multiple substances were assessed at baseline and follow-up. RESULTS: Most students (52.2%) were involved in >1 cyberbullying roles. Relative to no involvement, all cyberbullying roles, including witnessing only, were associated with increased odds of using most substances and polysubstance use at follow-up, after adjusting for sociodemographics and baseline substance use (odds ratios: 1.44 [95% confidence interval: 1.18-1.76] to 5.24 [2.73-10.05]). Relative to the witness-only role, students involved in all three roles were at greater odds of using several substances at follow-up (odds ratios: 1.47 [95% confidence interval: 1.05-2.05] to 2.96 [1.60-5.50]). CONCLUSIONS: Cyberbullying involvement, even witnessing, may be associated with future substance use in adolescence. All cyberbullying roles warrant consideration in understanding and preventing youth substance use.

BACKGROUND: Experiences of childhood adversity are consistently associated with compromised behavioral health later in life. Less clear is the intergenerational influence of maternal childhood adversity on developmental outcome in children. Completely unknown are the mechanisms linking teen mother's childhood adversity to child developmental outcomes. OBJECTIVE: The present study tested whether aspects of parenting (parenting stress, physical discipline, and disagreement with grandparents) served as the pathways between teen mother's childhood adversity and the externalizing behaviors of their offspring at age 11, by gender. PARTICIPANTS AND SETTING: Data were from a longitudinal panel study of teen mothers and their children, the Young Women and Child Development Study (N = 495; 57% male). METHODS: The pathways from teen mother's childhood adversity to their offspring's externalizing behavior were tested by two subscales: rule-breaking behavior and aggressive behavior. In addition, multiple-group analysis was examined for potential gender differences. RESULTS: Teen mother's childhood adversity was positively associated with greater use of parenting stress (ß = 0.16, p < .01) and physical discipline (ß=0.11, p < .05). In addition, parenting stress, physical discipline, and disagreement with grandparent were all associated with increased rule-breaking and aggressive behaviors in children. Multiple group analysis revealed that the path between physical discipline and externalizing behavior differed by gender, with the path only significant for girls. CONCLUSIONS: These findings have implications for early intervention efforts that emphasize the need to intervene with children and parents, particularly helping teen mothers gain knowledge and skills to offset the impact of their experiences of childhood adversity on their parenting behaviors.

Greater diversification of nicotine products, marijuana products, and prescription drugs have contributed to increasing trends in adolescent poly-product use-concurrent use of 2 or more drugs-within these drug classes (e.g., nicotine use via e-cigarettes, hookah, cigars). Extant work suggests that poly-product drug use disparities may be disproportionately heightened among youth from lower socioeconomic status (SES) backgrounds, however, it is unknown whether indicators of objective SES or subjective SES differentially increase risk of poly-product use including these newly emerging drugs. This study examined associations of parental education and subjective social status (SSS: perceptions of social standing compared to society [societal SSS] or school [school SSS]) with poly-product use of nicotine products, marijuana products, and prescription drugs among adolescents (Nâ¯=â¯2218). Lower parental education and school SSS were associated with increased odds of past or current single, dual, or multiple product use of nicotine, marijuana, and prescription drugs. Findings suggest that risk for poly-product use of emerging drugs are higher for adolescents who endorse lower perceived social standing relative to peers at school and who were from a lower parental SES background.

OBJECTIVE: This study had two main goals: to examine the structure of co-occurring peer bullying experiences among adolescents in South Korea from the perspective of victims and to determine the effects of bullying on suicidal behavior, including suicidal ideation and suicide attempts, among adolescents. METHOD: This study used data gathered from 4,410 treatment-seeking adolescents at their initial visits to 31 local mental health centers in Gyeonggi Province, South Korea. The structure of peer bullying was examined using latent class analysis (LCA) to classify participants' relevant experiences. Then, a binomial logistic regression adjusted by propensity scores was conducted to identify relationships between experiences of being bullied and suicidal behaviors. RESULTS: The LCA of experiences with bullying revealed two distinct classes of bullying: physical and non-physical. Adolescents who experienced physical bullying were 3.05 times more likely to attempt suicide than those who were not bullied. Victims of (non-physical) cyber bullying were 2.94 times more likely to attempt suicide than were those who were not bullied. CONCLUSIONS: Both physical and non-physical bullying were associated with suicide attempts, with similar effect sizes. Schools and mental health professionals should be more attentive than they currently are to non-physical bullying.
