RESUMEN

When human remains are inadvertently located, case-related circumstantial information is used to generate an identification hypothesis, and the preservation of the remains typically informs which identification methods may then be used to validate that hypothesis. What happens, however, when there is no contextual information to generate an identification hypothesis? This paper presents the case of a near-complete human skeleton discovered at Sandy Point in Victoria, Australia. The circumstances of the case did not facilitate an identification hypothesis, and with no hypothesis to triage the identification process, all possible identification methods were employed. Preservation of the individual meant neither a visual nor a fingerprint identification was possible, and the lack of an identification hypothesis meant there was no antemortem reference data to compare with the postmortem DNA or dental information. Consequently, in addition to historical research, novel methods, such as radiocarbon dating and genetic intelligence, were utilized to complement information provided by the forensic anthropology and odontology analyses, which ultimately resulted in the identification. This example highlights the complexity of cases of unidentified skeletal remains and emphasizes the fact that identification is a process that necessarily requires a multidisciplinary and collaborative approach. Key points: Human skeletal remains were recovered from Sandy Point, Victoria.The absence of circumstantial information and the poor preservation (i.e. skeletonized) of the remains precluded the formation of an identification hypothesis, rendering the identification process complex.Only through the integration of anthropology, odontology, molecular biology, radiocarbon dating, historical research, and genealogy were the remains able to be identified as Mr. Christopher Luke Moore, who drowned in 1928.Human identification is a process that necessarily requires a multidisciplinary and collaborative approach.

RESUMEN

PURPOSE: To examine the effects of exposure to dating violence and cyber victimization of female university students on resilience and happiness levels. METHODS: The data of this descriptive and correlational study were obtained from 400 female students studying at the Faculty of Health Sciences and Nursing between December 2021 and April 2022 via a personal information form, the Cyber Victim Scale (CVS), the Brief Resilience Scale (BRS), and the Oxford Happiness Inventory - Brief Form (OHI). In data analysis, Independent Samples t-Test, Pearson Correlation, and Linear Regression analysis were used together with descriptive statistics. RESULTS: Of the students, 6.5 % were exposed to physical, 8.3 % to economic, 9.8 % to sexual, 28.8 % to verbal, and 53.8 % to emotional dating violence. A significant difference was found between students' exposure to verbal (p = 0.013) dating violence and their resilience. A significant difference was also found between students' exposure to verbal and sexual (p = 0.04) dating violence and their happiness. There was a significant, negative, poor correlation between the mean of the female students' CVS scores and the BRS (r = -0.178, p < 0.001) and OHI scores (r = -0.247, p < 0.001). It was concluded that cyber victimization is a risk factor for resilience and happiness of the female university students. CONCLUSION: Early detection of dating violence and cyber victimization among university students is important in combating violence. In addition, considering that cyber victimization affects the level of psychological resilience and happiness, students' awareness of cyber victimization should be increased in the fight against cyber victimization to increase the mental health of young people.

RESUMEN

Background: Young men who have sex with men and young transgender women (YMSM-YTW) use online spaces to meet sexual partners with increasing regularity, and research shows that experiences of racism online mimics the real world. Objective: We analyzed differences by race and ethnicity in web-based and mobile apps used to meet sexual partners as reported by Chicago-based YMSM-YTW in 2016-2017. Methods: A racially and ethnically diverse sample of 643 YMSM-YTW aged 16-29 years were asked to name websites or mobile apps used to seek a sexual partner in the prior 6 months, as well as provide information about sexual partnerships from the same period. We used logistic regression to assess the adjusted association of race and ethnicity with (1) use of any website or mobile apps to find a sexual partner, (2) use of a "social network" to find a sexual partner compared to websites or mobile apps predominantly used for dating or hookups, (3) use of specific websites or mobile apps, and (4) reporting successfully meeting a sexual partner online among website or mobile app users. Results: While most YMSM-YTW (454/643, 70.6%) used websites or mobile apps to find sexual partners, we found that Black non-Hispanic YMSM-YTW were significantly less likely to report doing so (comparing White non-Hispanic to Black non-Hispanic: adjusted odds ratio [aOR] 1.74, 95% CI 1.10-2.76). Black non-Hispanic YMSM-YTW were more likely to have used a social network site to find a sexual partner (comparing White non-Hispanic to Black non-Hispanic: aOR 0.20, 95% CI 0.11-0.37), though this was only reported by one-third (149/454, 32.8%) of all app-using participants. Individual apps used varied by race and ethnicity, with Grindr, Tinder, and Scruff being more common among White non-Hispanic YMSM-YTW (93/123, 75.6%; 72/123, 58.5%; and 30/123, 24.4%, respectively) than among Black non-Hispanic YMSM-YTW (65/178, 36.5%; 25/178, 14%; and 4/178, 2.2%, respectively) and Jack'd and Facebook being more common among Black non-Hispanic YMSM-YTW (105/178, 59% and 64/178, 36%, respectively) than among White non-Hispanic YMSM-YTW (6/123, 4.9% and 8/123, 6.5%, respectively). Finally, we found that while half (230/454, 50.7%) of YMSM-YTW app users reported successfully meeting a new sexual partner on an app, Black non-Hispanic YMSM-YTW app users were less likely to have done so than White non-Hispanic app users (comparing White non-Hispanic to Black non-Hispanic: aOR 2.46, 95% CI 1.50-4.05). Conclusions: We found that Black non-Hispanic YMSM-YTW engaged with websites or mobile apps and found sexual partners systematically differently than White non-Hispanic YMSM-YTW. Our findings give a deeper understanding of how racial and ethnic sexual mixing patterns arise and have implications for the spread of sexually transmitted infections among Chicago's YMSM-YTW.

RESUMEN

In the present study, we have characterized the complete chloroplast (Cp) genome of Meconopsis torquata Prain (family Papaveraceae), revealing the plastome size of 153,290 bp, and a GC content of 38.72 %. The cp genome features the typical circular quadripartite structure found in flowering plants, including a pair of inverted repeat regions (25,816 bp), isolated by a small single-copy region (17,740 bp) and a large single-copy (83,918 bp). Genome annotation revealed 132 genes: 87 protein-coding genes, 37 tRNAs and eight rRNAs. This comparative study demonstrated that the genome structure, gene number and GC ratio are consistent with several other cp genomes of Meconopsis and Papaver genera. A total of 120 SSRs were detected in the plastome, the majority (111) of which were mononucleotide repeats. Among the longer repeats, palindromic sequences were most common, followed by forward, reverse, and complement repeats. The whole genome alignment revealed the conserved nature of the inverted repeat region over single-copy zones. Nucleotide diversity unveiled hypervariable sites (ycf1, rps16, accD, atpB and psbD) in both the small and large single-copy regions, which could be useful for designing molecular markers for taxonomic identification. Phylogenetic analysis revealed a close alliance of M. torquata with other Meconopsis species, such as M. pinnatifolia and M. paniculata, with strong bootstrap support. Molecular dating suggests that M. torquata originated during the Tortonian age of the Miocene epoch of the Cenozoic era. These findings provide valuable insights for biological research, especially in understanding the genetic and evolutionary divergence within the Papaveraceae family.

RESUMEN

Studies have shown that there are protective and risk factors related to cyber dating violence. However, the effect size of these factors is unclear. This study aims to clarify the effect size of the associations of protective and risk factors, as well as symptoms of mental health conditions, with cyber dating violence perpetration and victimization. Databases, including PubMed, Web of Science (WoS), ProQuest, Scopus, and EBSCOhost were searched to identify relevant studies. Forty-nine studies were included in the current study. Results revealed statistically significant and medium relationships between cyber dating violence perpetration and some risk factors, including offline dating violence perpetration-related factors (i.e., physical, psychological, sexual, relational, verbal/emotional, and threat) and offline dating violence victimization-related factors (i.e., physical and psychological); and small relationships with other risk factors (i.e., sexual offline dating violence victimization, attachment styles, and jealousy), protective factors (i.e., family support and emotional regulation), and mental health symptoms (i.e., depression, anxiety, and alcohol use). There was also statistically significant and robust relationship between cyber dating violence victimization and verbal/emotional offline dating violence victimization (i.e., risk factor); medium relationships with some risk factors, including offline dating violence perpetration-related factors (i.e., psychological and verbal/emotional) and offline dating violence victimization-related factors (i.e., physical, psychological, sexual, relational, and threat); small relationships with other risk factors (i.e., physical offline dating violence perpetration, attachment styles, childhood sexual abuse), protective factors (i.e., family support, emotional regulation, and self-esteem), and mental health symptoms (i.e., depression, anxiety, stress, alcohol use, and drug use). The study's results highlight risk and protective factors associated with cyber dating violence and demonstrate its association with mental health symptoms.

RESUMEN

BACKGROUND: Endemic plants are key to understanding the evolutionary history and enhancing biodiversity within their unique regions, while also offering significant economic potential. The East Asian endemic genus Corchoropsis Siebold & Zucc., classified within the subfamily Dombeyoideae of Malvaceae s.l., comprises three species. RESULTS: This study characterizes the complete plastid genomes (plastomes) of C. crenata var. crenata Siebold & Zucc. and C. crenata var. hupehensis Pamp., which range from 160,093 to 160,724 bp. These genomes contain 78 plastid protein-coding genes, 30 tRNA, and four rRNA, except for one pseudogene, infA. A total of 316 molecular diagnostic characters (MDCs) specific to Corchoropsis were identified. In addition, 91 to 92 simple sequence repeats (SSRs) in C. crenata var. crenata and 75 in C. crenata var. hupehensis were found. Moreover, 49 long repeats were identified in both the Chinese C. crenata var. crenata and C. crenata var. hupehensis, while 52 were found in the South Korean C. crenata var. crenata. Our phylogenetic analyses, based on 78 plastid protein-coding genes, reveal nine subfamilies within the Malvaceae s.l. with high support values and confirm Corchoropsis as a member of Dombeyoideae. Molecular dating suggests that Corchoropsis originated in the Oligocene, and diverged during the Miocene, influenced by the climate shift at the Eocene-Oligocene boundary. CONCLUSIONS: The research explores the evolutionary relationships between nine subfamilies within the Malvaceae s.l. family, specifically identifying the position of the Corchoropsis in the Dombeyoideae. Utilizing plastome sequences and fossil data, the study establishes that Corchoropsis first appeared during the Eocene and experienced further evolutionary divergence during the Miocene, paralleling the evolutionary patterns observed in other East Asian endemic species.

RESUMEN

Men who have sex with men are at an increased risk of acquiring sexually transmitted infections, and although behavioral and contextual interventions have improved, infections continue to spread. Therefore, a new focus on recent trends in sexual health in this population is needed. The aim of this study was to describe the relationship between sociodemographic and behavioral characteristics according to Grindr usage patterns, the prevalence of sexually transmitted infections (STIs), and attitudes toward HIV testing. In January 2020, a cross-sectional study was conducted using a sample of 881 men who have sex with men (MSM) who completed an online questionnaire. We evaluated their Grindr use patterns (moderate or intensive) and explored the associations of these with sociodemographic behavioral characteristics, STIs, and attitudes toward HIV testing. Of 881 participants in total, 587 (66.6%) were intensive Grindr users. Compared to moderate users, these participants reported significantly higher numbers of casual sexual partners (76.2% vs. 23.8%; p < 0.001), were more likely to participate in Chemsex (77.3% vs. 22.7%: p = 0.031), and had a higher self-reported number of STIs (69.9% vs. 30.1; p = 0.046). They also demonstrated better attitudes toward HIV testing (69.7% vs. 30.3%; p = 0.045) and perceived themselves to be at moderate risk of HIV (71.2% vs. 28.8%: p = 0.048). Moreover, intensive Grindr users were 1.36 times more likely than moderate users to test positive for STIs (95%CI = 1.15-1.91; p = 0.048). With some limitations, age, sexual partners, intensive Grindr users, and PrEP uses were associated with the risk of STIs in the sample of Spanish Grindr users studied. As Grindr users are vulnerable to sociodemographic and behavioral factors that determine STIs and HIV infection, mainly among intensive users, it is necessary to highlight the importance of new trends such as online dating apps, PrEP use, substance use in sex, and Chemsex, and these need to be incorporated into online public health strategies.

RESUMEN

Dating violence victimization is a pervasive public health problem that affects individuals of all age groups, but it holds particular significance during adolescence due to the potential long-term consequences on an individual's physical and psychological well-being, and potential influence on the health of adult relationships. Although there is now ample research on the topic of adolescent dating violence prevalence, risk factors, and consequences, to our knowledge, only four studies have assessed dating violence victimization among autistic youth. The current study was designed to investigate the prevalence of, and risk markers for, dating violence victimization among autistic youth. Specifically, the study had two aims: (a) to estimate the prevalence of dating violence victimization among autistic youth in a U.S.-based sample and (b) to identify correlates of dating violence for autistic youth, which include sociodemographic, mental health, and alcohol-related variables. We found that among participants who were in a romantic relationship in the past year, autistic participants were not any less likely to experience dating violence victimization compared to their non-autistic counterparts (40.7% for autistic youth vs. 38.0% for non-autistic youth). In addition, findings from the current study demonstrate the significant relationships between dating violence victimization and consequences of alcohol use, loneliness, and anxiety among autistic youth. Existing studies, in addition to the results of the current study, suggest the need for tailored dating violence prevention, support, and intervention to support the overall well-being of autistic youth.

RESUMEN

Leading theories of the recent history of sexuality have pointed to trends toward detraditionalization and precarity in intimate relations, but also to democratization and innovation. This study grounded in 79 qualitative interviews with men seeking men online considers their experiences in light of these theories. The rise of dating apps has generated sexual fields that have shaped the sexual subjectivities of the current era in multiple ways. The narratives of study participants show much more than the hook-up culture that dating apps are best known for. They speak to experiences of superficiality, unmet expectations, and sometimes bruising intersections with hierarchies defined by age, race, body type, gender expression, and serostatus. Yet at the same time, they show a strong aspiration to sociability, social network building, and reach for a language of affiliation beyond the kin and friendship terms of the larger society. Generational comparisons indicate the shifting sexual subjectivities that dating apps have shaped by constituting virtual sexual fields.

RESUMEN

Titanite-bearing calc-silicates and mafic gneisses, metamorphosed under amphibolite- to granulite-facies conditions, crop out in Val d'Ossola area (Ivrea-Verbano Zone, Italy). The Ivrea-Verbano Zone represents an exhumed section of the pre-Alpine middle to lower continental crust which escaped the Alpine subduction, thus provides a unique opportunity to study continental crustal processes and evolution. Among several samples, three, collected from different locations, were chosen for detailed analyses of titanite. Petrochronology of titanite was performed with Laser ablation split-stream (LASS) technique on petrographic thin sections. Petrochronological results on titanite do not define clear correlations with chemistry except for one sample. Rare earth elements (REE) patterns of titanite from the three samples are apparently different in terms of average concentration (i.e., lower or upper 1000 times CI), shapes and occurrence or absence of Eu negative anomaly. Al/Fe vs ΣLREE and Fe content vs Zr/Y plots show that the studied samples coincide with metamorphic rock field deriving from calc-silicates and mafic protoliths, as previously demonstrated in literature. Any compilations of petrochronological data on titanite from the metamorphic volcano-sedimentary sequence of Val d'Ossola can be found in literature. Therefore, these data represent a new insight on an accessory mineral phase whose significance and scientific interest are rising in the last years. Future studies of the evolution of these kinds of rock, widespread in the high-grade metamorphic basements, will benefit from these data as a term of comparison.

RESUMEN

High concentrations of microplastics (MPs) have been documented in the deep-sea surface sediments of the Arctic Ocean. However, studies investigating their high-resolution vertical distribution in sediments from the European waters to the Arctic remain limited. This study examines MPs in five sediment cores from the Norwegian Coastal Current (NCC), encompassing the water-sediment interface and sediment layers up to 19 cm depth. Advanced analytical methods for MP identification down to 11 µm in size were combined with radiometric dating and lithology observations. MPs were present across all sediment cores, including layers predating the introduction of plastics, with concentrations exhibiting significant variation (54-12,491 MP kg-1). The smallest size class (11 µm) predominated in most sediment layers (34-100%). A total of 18 different polymer types were identified across all sediment layers, with polymer diversity and depth correlations varying widely between stations. Our findings suggest that differences in seafloor topography and the impact of anthropogenic activities (e.g., fishing) lead to varying environmental conditions at the sampling sites, influencing the vertical distribution of MPs. This challenges the reliability of using environmental parameters to predict MP accumulation zones and questions the use of MPs in sediment cores as indicators of the Anthropocene.

RESUMEN

This article describes the development of an instrument used to evaluate the perceived self-efficacy of school staff in addressing dating violence (DV) among youth. The study employed a mixed exploratory sequential design. First, a series of items was elaborated upon based on the scientific literature on self-efficacy and material from 15 semi-structured interviews conducted with school staff. Then, a sample of 110 school staff members answered an online survey. An exploratory factor analysis revealed a two-factor structure reflecting dimensions of self-efficacy in addressing DV: communicating DV content to youth (α = .93) and the ability to intervene with youth who experience DV (α = .91). The scale could offer a means to assess the effectiveness of training offered to school counselors and teachers regarding DV prevention.

RESUMEN

Dating violence is often perpetrated among adolescents, which increases the efforts to better understand individual risk factors for preventive efforts. Although multiple forms (i.e., physical and psychological) often coexist, few studies have studied the chronicity and developmental classes of physical teen dating violence and examined whether subtypes of trait anger predict teen dating perpetration over time. Thus, the purpose of the current study is to investigate: (a) the developmental group-based patterns of physical teen dating violence; and (b) whether subtypes of trait anger expression predict association in these classes using the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2007 to 2013 dataset. Group-based trajectory modeling results identified four classes of teen dating violence perpetration (e.g., Accelerating, Abstaining, Desisting, and High Chronic). Multinomial logistic regression results indicated that expressing anger outwardly was positively associated with Desisting and High Chronic patterns, but not Accelerating patterns. These results suggest that there are four classes of teen dating violence perpetration and underscore the effects of expression of trait anger as a risk factor of teen dating violence perpetration. Practical and theoretical implications are discussed.

RESUMEN

Objective: This study aimed to investigate the factors associated with online dating among college students engaging in casual sexual behavior, by understanding these factors, targeted intervention measures can be formulated for relevant departments to help college students better manage their sexual health and offer useful reference for the development of sexual health education. Methods: A cross-sectional survey was conducted using a stratified cluster sampling method. Demographic and behavioral information was gathered through questionnaires for univariable and multivariable logistic regression analysis. Results: A total of 595 college students engaging in casual sexual behavior were included in the study, of whom 345 (57.98%) had found casual sexual partners through the internet. Multiple regression analysis indicated that male participants, those aged 20-21 years, those who had recently attended AIDS-themed lectures or health education classes at school, participants who were willing to engage in commercial sexual activities during online dating, participants who accepted sexual activities among men who have sex with men (MSM), those who reported having sexual intercourse with regular partners in the past year, participants who wanted to know if their online dating partners were HIV-diagnosed, those who had engaged in commercial sexual behavior in the past year and those who perceived themselves to be at risk of HIV infection were more likely to engage in online dating. Participants with general/disharmonious family relationships, those who consistently used condoms during casual sexual behavior and those who occasionally used condoms were less likely to engage in online dating. Conclusion: There were a certain extent proportion of casual partners among college students were sourced from the internet, indicating the profound influence of online dating on casual sexual behavior. Therefore, future research and intervention measures should focus on sexual health education and promotion on online dating platforms, strengthen regulations and guidance on college students' online dating behavior, and raise awareness of HIV prevention in this group.

RESUMEN

Romantic relationships are vital for health, well-being and quality of life, and an increasing percentage of romantic relations begin via use of dating apps and subsequently progress to dates. In the present study we examined dating application use and dates among individuals with SAD (n = 54) and without SAD (n = 54). Our sample included young adults (age range 18 to 33) who were not in a romantic relationship at the time of the study. For both individuals with SAD and without SAD, half of the participants were men, and half were women. We used a daily diary measurement in which participants reported on their dating application use and dates, as well as on concomitant emotions and perceptions for 21 consecutive days. We found that individuals with and without SAD did not differ in the frequency/duration of application use nor in the number of dates attended. However, individuals with SAD experienced dates as more negative compared to individuals without SAD (Cohen's d = 0.65). Interestingly, individuals with SAD did not significantly differ in their experience of dates as positive compared to individuals without SAD. Moreover, use of dating applications/going on dates were associated with increases in shame (Cohen's d = 0.59) and embarrassment (Cohen's d = 0.45) and this was found to a greater extent among individuals with SAD compared to individuals without SAD (Cohen's d = 0.50, 0.39 for shame and embarrassment respectively). Findings are discussed in the context of cognitive behavioral models of SAD and implications for treatment are considered.

RESUMEN

A sizeable literature has shown that child marriage is associated with an increased risk for intimate partner violence (IPV). However, this research has been cross-sectional, and the temporality of the association has not been investigated. Specifically, no study has yet examined whether IPV is a predictor of child marriage and adolescent pregnancy. This study uses prospective longitudinal data on a cohort of adolescent girls from the Malawi Longitudinal Study of Families and Health to evaluate whether IPV victimization predicts child marriage or adolescent pregnancy. Using survival models, we find that adolescent girls who experienced physical IPV (measured at survey baseline, in 2017-2018) are more likely to enter child marriages (measured at survey follow-up, in 2021) (hazard ratio [HR] = 2.7 [1.44, 5.08]). Experiencing sexual IPV is also significantly associated with adolescent pregnancy (HR = 1.97 [1.16, 3.33]). These findings indicate the need for greater intervention to ensure healthy adolescent relationships, as well as further research to understand how abusive relationships shape early transitions to adulthood.

RESUMEN

Silkmoths (Bombycidae) have a disjunct distribution predominantly in the Southern Hemisphere and Asia. Here we reconstruct the phylogenetic history of the family to test competing hypotheses on their origin and assess how vicariance and long-distance dispersal shaped their current distribution. We sequenced up to 5,074 base pairs from six loci (COI, EF1-α, wgl, CAD, GAPDH, and RpS5) to infer the historical biogeography of Bombycidae. The multilocus dataset covering 20 genera (80 %) of the family, including 17 genera (94 %) of Bombycinae and 3 genera (43 %) of Epiinae, was used to estimate phylogenetic patterns, divergence times and biogeographic reconstruction. Dating estimates extrapolated from secondary calibration sources indicate the Bombycidae stem-group originated approximately 64 Mya. The subfamilies Epiinae (South America) and Bombycinae (Australia, Asia, East Palaearctic, and Africa) were reciprocally monophyletic, diverging at c. 56 Mya (95 % credibility interval: 66-46 Mya). The 'basal' lineage of Bombycinae - Gastridiota + Elachyophtalma - split from the rest of Bombycinae c. 53 Mya (95 % credibility interval: 63-43 Mya). Gastridiota is a monobasic genus with a relictual distribution in subtropical forests of eastern Australia. The Oriental and African genera comprised a monophyletic group: the Oriental region was inferred to have been colonized from a long-distance dispersal event from Australia to South-East Asia c. 53 Mya or possibly later (c. 36-26 Mya); Africa was subsequently colonized by dispersal from Asia c. 16 Mya (95 % credibility interval: 21-12 Mya). Based on the strongly supported phylogenetic relationships and estimates of divergence times, we conclude that Bombycidae had its origin in the fragment of Southern Gondwana consisting of Australia, Antarctica and South America during the Paleocene. The disjunction between South America (Epiinae) and Australia (Bombycinae) is best explained by vicariance in the Eocene, whereas the disjunct distribution in Asia and Africa is best explained by more recent dispersal events.

RESUMEN

BACKGROUND: Sexual violence (SV) is a significant problem for sexual minorities, including men who have sex with men (MSM). The limited research suggests SV is associated with a host of syndemic conditions. These factors tend to cluster and interact to worsen one another. Unfortunately, while much work has been conducted to examine these factors in heterosexual women, there is a lack of research examining MSM, especially their SV risk perception. Further, MSM are active users of dating and sexual networking (DSN) mobile apps, and this technology has demonstrated usefulness for creating safe spaces for MSM to meet and engage partners. However, mounting data demonstrate that DSN app use is associated with an increased risk for SV, especially given the higher likelihood of using alcohol and other drugs before sex. By contrast, some researchers have demonstrated that DSN technology can be harnessed as a prevention tool for HIV; unfortunately, no such work has progressed regarding SV. OBJECTIVE: This study aims to (1) use qualitative and quantitative methods to tailor an existing laboratory paradigm of SV risk perception in women for MSM using a DSN mobile app framework and (2) subject this novel paradigm to a rigorous validation study to confirm its usefulness in predicting SV, with the potential for use in future prevention endeavors. METHODS: To tailor the paradigm for MSM, a team of computer scientists created an initial DSN app (G-Date) and incorporated ongoing feedback about the usability, feasibility, and realism of this tool from a representative sample of MSM. We used focus groups and interviews to assist in the development of G-Date, including by identifying relevant stimuli, developing the cover story, and establishing the appropriate study language. To confirm the paradigm's usefulness, we are conducting an experimental study with web-based and face-to-face participants to determine the content, concurrent, and predictive validities of G-Date. We will evaluate whether certain correlates of SV informed by syndemics and minority stress theories (eg, history of SV and alcohol and drug use) affect the ability of MSM to detect SV risk within G-Date and how paradigm engagement influences behavior in actual DSN app use contexts. RESULTS: This study received funding from the National Institute on Alcohol Abuse and Alcoholism on September 10, 2020, and ethics approval on October 19, 2020, and we began app development for aim 1 immediately thereafter. We began data collection for the aim 2 validation study in December 2022. Initial results from the validation study are expected to be available after December 2025. CONCLUSIONS: We hope that G-Date will enhance our understanding of factors associated with SV risk and serve as a useful step in creating prevention programs for this susceptible population.

RESUMEN

BACKGROUND: Prior studies have shown that marijuana use is often associated with physical teen dating violence. However, few studies have examined the longitudinal mediating effects of associating with antisocial peers and impulsivity on this relationship. Also, few studies have estimated the cascading developmental impact of marijuana use and antisocial peer association, predicting the continued marijuana use and antisocial peer associations while considering the risk of impulsivity in physical teen dating violence. Thus, the current study utilized the problem behavior theory and an alternative path to physical dating violence to address these limitations. OBJECTIVE: The current study tested the longitudinal effects of marijuana use on physical teen dating violence and the indirect effects of antisocial peer association and impulsivity on this relationship (M = 12.29); 52.1 % of males and 47.9 % of females participated. METHODS: Adolescents completed questionnaires at baseline and were assessed six months later (n = 836). Generalized structural equation modeling (GSEM) and cross-lagged mediation models were used first to analyze the direct effect of lifetime marijuana use on physical dating violence and antisocial peer association and impulsivity as potential mediators of this relationship. Then, the cross-lagged mediation models were used to estimate the alternative path to physical teen dating violence using lifetime marijuana use and antisocial peer association as predictors at baseline and continued antisocial peer association, marijuana use, and impulsivity at the subsequent wave as mediators. RESULTS: Results suggested that marijuana use at baseline was not positively associated with physical teen dating violence over time. The association with antisocial peers but not impulsivity mediated the relationship between marijuana use and physical dating violence. Cross-lagged mediation results suggested that marijuana use at baseline positively predicted antisocial peer association in the subsequent wave, which led to an increase in physical teen dating violence. Further, antisocial peer association at baseline is positively associated with continued antisocial peer association at the subsequent wave; thus, antisocial peer association is positively related to physical teen dating violence when controlling for depressive symptoms, family support, number of dates, and parental monitoring. CONCLUSION: These results suggest though marijuana use alone is not statistically associated with physical teen dating violence, it does increase the risk of antisocial social peer associations that could increase adolescents' likelihood to engage in physical teen dating violence. Further, the onset of antisocial peer association could persist over time, thus serving as a risk factor for physical teen dating violence over time.

RESUMEN

This study explores how climate variables influenced the evolution and diversification of Neurergus newts within the Irano-Anatolian biodiversity hotspot. We use a dated phylogenetic tree and climatic niche models to analyze their evolutionary history and ecological preferences. Using genetic data from nuclear (KIAA) and mitochondrial (16s and 12s) genes, we estimate divergence times and identify four major Neurergus clades. The initial speciation event occurred approximately 11.3 million years ago, coinciding with the uplift of the Zagros and Anatolian mountains. This geological transformation isolated newt populations, likely triggering the first speciation event. By integrating potential geographic distribution with climate variables, we reconstruct ancestral niche occupancy profiles. This highlights the critical roles of temperature and precipitation in shaping Neurergus habitat preferences and distribution. We observe both phylogenetic niche conservatism and divergence, with niche divergence playing a dominant role in diversification. This research emphasizes the complex interplay of geography, climate, and ecology in speciation and the vulnerability of isolated mountain newt populations to environmental changes.
