Background: Chlamydia trachomatis is the most prevalent bacterial sexually transmitted infection (STI) globally, linked to severe complications such as pelvic inflammatory disease and infertility. In the Brazilian Amazon, socioeconomic vulnerability and the absence of screening policies exacerbate risks, particularly among female sex workers (FSWs). Objective: This study aimed to determine the seroprevalence of anti-C. trachomatis IgG antibodies among FSWs in five municipalities of Pará State, Brazilian Amazon, and identify epidemiological factors associated with infection. Methods: A retrospective cross-sectional study (2005–2007) included 348 FSWs recruited via convenience sampling. Sociodemographic and behavioral data were collected through questionnaires, and blood samples were analyzed by ELISA for anti-C. trachomatis IgG. Statistical analyses included Fisher’s exact tests, odds ratios (ORs), and 95% confidence intervals (CIs), using SPSS 21.0. Results: Overall seroprevalence was 93.9% (327/348; 95% CI: 83.1–90%). Significant associations included a household income of 1–3 minimum wages (98.4%; p = 0.0002), sexual partners from the same region (98.8%; p = 0.0421), and age >42 years (96.3%). Most reported inconsistent condom use (43.7%), multiple monthly partners (54.6%), and illicit drug use (53.4%). Discussion: The extremely high seroprevalence reflects chronic C. trachomatis exposure, driven by socioeconomic deprivation and limited healthcare access. Comparisons with global data underscore the urgent need for screening policies, absent in Brazil for FSWs, and highlight the vulnerability of this population. Conclusions: The findings reveal an alarming burden of C. trachomatis exposure among Amazonian FSWs. Integrated strategies, including routine screening, sexual health education, and inclusion of FSWs in priority health programs, are critical to reduce transmission and associated complications.

Background/Objectives: Early experiences can significantly influence brain development, particularly when they occur during specific time windows known as sensitive or critical periods. Therefore, the early promotion of neurodevelopmental functions is crucial in children at risk for neurodevelopmental disabilities, such as those with cerebral palsy. This article introduces AMIRA (A Multidimensional and Integrated Rehabilitation Approach), a rehabilitative framework designed for infants at risk of neurodevelopmental disabilities. Methods: AMIRA is intended to guide clinical–rehabilitation reasoning rather than prescribe a rigid sequence of predetermined activities for the child. The theoretical foundation and structure of AMIRA are presented by formalizing its criteria, objectives, tools, and intervention procedures. The framework comprises four distinct sections, each supported by adaptive strategies to facilitate access to materials and to promote play-based interactions among the child, their environment, and communication partners. Particular attention is given to optimizing both micro- and macro-environments for children with, or at risk of, co-occurring visual impairment. Each rehabilitative section includes three progressive phases: an initial observation phase, a facilitation phase to support the child’s engagement, and an active experimentation phase that gradually introduces more challenging tasks. Results: The intervention pathways in AMIRA are organized according to six core developmental domains: behavioral–emotional self-regulation, visual function, postural–motor skills, praxis, interaction and communication, and cognitive function. These are outlined in structured charts that serve as flexible guidelines rather than prescriptive protocols. Each chart presents activities of increasing complexity aligned with typical developmental milestones up to 24 months of age. For each specific ability, the corresponding habilitation goals, contextual recommendations (including environmental setup, objects, and tools), and suggested activities are provided. Conclusions: This study presents a detailed intervention approach, offering both a practical framework and a structured set of activities for use in rehabilitative settings. Further studies will explore the efficacy of the proposed standardized approach. Full article

The Norwegian construction sector has long struggled with conflict, particularly in large-scale and complex projects, where adversarial practices, rigid procurement systems, and insufficient early collaboration are common. This study explores how partnering contracts, which are collaborative delivery models designed to align stakeholder interests, affect conflict dynamics in real-world settings. Employing a mixed-methods approach, it combines semi-structured interviews with 21 experienced Norwegian construction professionals and a structured survey of 33 industry experts. The findings reveal that partnering can foster trust, improve communication, and reduce adversarial behavior through mechanisms such as early contractor involvement, joint goal setting, and open dialogue. However, participants also identified critical risks: superficial collaboration rituals, ambiguous roles, and unresolved structural inequalities that can exacerbate tensions. Importantly, the study emphasizes that partnering success depends less on the contract itself and more on cultural alignment, stakeholder competence, and long-term relational commitment. These insights contribute to a more nuanced understanding of how collaborative contracting influences conflict mitigation in the Norwegian construction sector. Full article

This study investigates how demographic characteristics, severity of intimate partner violence (IPV), social support, gender equality awareness, and demographic factors (e.g., living with children at home) influence help-seeking behaviors among 2527 IPV-experienced women in Beijing, Shanghai, Guangzhou, and Shenzhen. Drawing on the help-seeking model and conservation of resource theory, the study distinguishes between formal (e.g., police, legal aid) and informal (e.g., family, friends) help-seeking. Logistic regression results reveal that greater violence severity, stronger perceived social support, and higher gender equality awareness significantly increase both formal and informal help-seeking. Notably, living with children is associated with a higher likelihood of seeking formal help, possibly due to increased concerns for children’s safety and the desire to change the abusive environment. While help-seeking behavior is on the rise overall, particularly among women with strong support networks and progressive gender attitudes, structural and cultural barriers remain. The findings underscore the need to improve public education, reduce stigma, and enhance accessibility of support systems. This study contributes to the growing literature on IPV in China and provides evidence for refining policy interventions and service delivery. Full article

Background: Teen dating violence (TDV) is a serious public health concern, with sexual and gender minority youth (SGMY) at elevated risk due to minority stress and systemic inequalities. This systematic review examines individual, relational, and contextual risk factors for TDV among SGMY. Methods: A systematic search was conducted in Scopus, Web of Science, and APA PsycInfo on 10 December 2024. Studies published between 2014 and 2024 focusing on teen dating violence (TDV) as an outcome among sexual and gender minority youth (SGMY) aged 13–19 were included. Study selection was independently performed by multiple reviewers using Rayyan. Risk of bias was assessed using the JBI Critical Appraisal Tools. Due to heterogeneity in the study design and measurement tools, a narrative synthesis was conducted. Results: Six risk domains emerged: (1) Demographic/Identity (e.g., gender, orientation, or race); (2) Psychological/Behavioral (e.g., distress or substance use); (3) Violence/Bullying (e.g., cyberbullying or exclusion); (4) Family/Sexual Abuse (e.g., family rejection); (5) Relational/Social (e.g., partner outing); and (6) School/Community (e.g., non-inclusive environments). Bisexual, pansexual, transgender, and racialized youth showed heightened vulnerability. Most studies were conducted in the USA and relied on non-validated TDV measures and cross-sectional designs, limiting comparability and causal inference. Conclusions: SGMY face unique, often overlooked TDV risks. There is a need for intersectional, longitudinal research and inclusive, developmentally appropriate prevention efforts that address both relational and structural factors. This review received no external funding and was not registered. Full article

This study introduces and validates a novel instrument to measure aggressive gender backlash (AGB), a distinct and underexplored dimension of gender backlash (GB) within intimate partner relationships. Based on the General Aggression Model, a multidimensional scale was developed and tested using data from 513 Peruvian female microentrepreneurs. Results demonstrate solid evidence of reliability, discriminant validity, and predictive validity across five dimensions: hostility, the withdrawal of support, sabotage/coercion, gender stereotyping, and masculine victimization. The findings reveal that AGB is more prevalent than intimate partner violence against women (IPVAW) and often precedes it. AGB encompasses covert, non-violent behaviors that aim to resist female empowerment, such as emotional sabotage, manipulation, and disqualification, often normalized within relationships. This construct is significantly associated with lower levels of empowerment, increased subordination, emotional morbidity, and decreased work productivity. This study redefines GB as an interpersonal process measurable at the individual level and provides the first validated tool for its assessment. By conceptualizing AGB as a persistent, harmful, and functionally equivalent mechanism to IPVAW, though not necessarily physically violent, this research fills a key gap in gender violence literature. It offers practical implications for early detection and prevention strategies. Full article

We assessed economic vulnerability, measured by food insecurity, in relation to primary risk behaviors for adolescent pregnancy among U.S. adolescent females. The survey data for this cross-sectional study were collected from adolescent females (n = 187) recruited from high schools (n = 18) serving low-income communities in Southern California between January 2022 and July 2023. We used crude and adjusted logistic regression models to assess associations between food insecurity and sexual risk behaviors for adolescent pregnancy (e.g., early age of sexual initiation, contraceptive use, condom use), as well as financial dependence on a male partner. Adjusted models included demographics significantly associated with outcome variables. Participants were, on average, 17 years old (SD = 1.48); most participants were born in the U.S. (90.3%) and identified as Latina/Hispanic (85.0%). In crude and adjusted bivariate logistic regression models, compared to participants not reporting food insecurity, participants who reported food insecurity were (1) more likely to report early age at first sex (aOR: 3.6, 95% CI: 1.1–11.7), (2) less likely to report condom use in the previous six months among those sexually active during that timeframe (aOR = 0.2, 95% CI: 0.1–0.6), and (3) more likely to report being financially dependent on a male partner (aOR: 4.2. 95% CI: 1.6–11.3). The findings suggest the importance of addressing economic vulnerability to reduce risk factors for adolescent pregnancy. Full article

Objective: Marital infidelity significantly impacts both the community and the institution of marriage. This study aims to develop a theoretical framework for analyzing marital infidelity through a game-theoretic lens. Methodology/Design/Approach: This research employs a game-theoretic model to predict the decision-making processes of unfaithful partners. Static game models are utilized to explore the interactions between spouses, focusing on identifying Nash equilibria that encapsulate the complexities and uncertainties inherent in infidelity-related decisions, whether through pure or mixed strategies. Results: The analysis reveals strategic dynamics in marital infidelity, where Nash equilibria indicate scenarios where one or both partners may engage in extramarital affairs. A Nash equilibrium is established when both partners perceive the benefits of infidelity as outweighing the costs, leading to diminished trust and communication. The Mixed-Strategy Nash Equilibrium (MSNE) hypothesis suggests that spouses may oscillate between fidelity and infidelity based on probabilistic strategies. Research Implications: This study provides a game-theoretic perspective on marital infidelity, whose findings may be used to inform legal frameworks and social policies addressing the consequences of infidelity, potentially impacting family counseling and legal services. Value/Originality: This research introduces a game-theoretic approach to understanding trust and transgression in marriages, identifying two primary categories of Nash equilibria. It fills a theoretical gap while providing practical insights into marital behavior. Full article

Background/Objectives: Sexual attitudes, particularly those on the erotophilia (positive openness) to erotophobia (negative fear) scales, play a critical role in shaping behaviors and health decisions. While associations between sexual behavior and substance use have been documented, limited research has explored how sexual attitudes relate to mental health and substance use among Latin American university populations. This study aimed to examine the associations among erotophilic attitudes, mental health symptoms (anxiety and depression), substance use risk, and sexual behaviors in Mexican university students. Methods: A cross-sectional observational study was conducted between 2019 and 2023 with 1475 undergraduate students aged 17–25 years. Participants completed the Revised Sexual Opinion Survey (R-SOS) to assess sexual attitudes, the Hospital Anxiety and Depression Scale (HADS) for mental health evaluation, and adapted items from the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) to measure substance use risk. Erotophilic attitudes were defined as R-SOS scores ≥ 70. Statistical tests included the Kolmogorov–Smirnov test for normality, t-tests or Mann–Whitney U tests for group comparisons, Fisher’s exact test for categorical variables, and Spearman’s correlations. Multivariate binary logistic regression was used to calculate adjusted odds ratios (AdORs) and 95% confidence intervals (CIs), with a significance level of p < 0.05. Results: Erotophilic students were more likely to be male, older, initiate sexual activity earlier, and report a greater number of sexual partners. Erotophilia was positively associated with anxiety and tobacco, alcohol and marijuana use, and negatively associated with depressive symptoms. Multivariate analysis indicated that erotophilia was independently associated with male sex, age ≥ 20, higher anxiety, lower depression, low socioeconomic status, and increased risk of tobacco and marijuana use. Lower rates of consistent condom use were also reported among erotophilic individuals. Conclusions: Erotophilia may serve as a behavioral risk marker linked to anxiety symptoms and increased substance use, but not to depression. These findings highlight the need for integrated interventions addressing sexual health, substance use, and mental well-being in university populations. Full article

Community-Engaged Research (CER) arose as a means of increasing the democratic participation of communities that study outcomes directly impact. CER has been identified as a recommended approach for conducting biomedical and behavioral health research with Black communities, a population that has been excluded from and exploited by academic health research for centuries. However, solely increasing community participation without identifying and redressing racialized power imbalances within community–academic partnerships involving Black populations can stall progress towards racial health equity. The purpose of this study was to explore how power can be redistributed equitably in community–academic health research partnerships involving Black populations. Utilizing the qualitative methodological approach of critical narrative inquiry, counter-stories from 12 Black individuals who have served as community partners on U.S.-based academic health research teams were collected via in-depth semi-structured narrative interviews. A reflexive thematic analysis approach was utilized to identify and analyze strategies expressed by study participants for increasing community agency, efficacy, and solidarity in health research. By centering the voices of Black community members who have directly engaged with academic health research institutions, this study sought to amplify the desires and aspirations of Black communities regarding shifting power in health research processes and outcomes.

Although the help-seeking behaviors of intimate partner violence survivors have been imperative, less evidence has been shown on ethnic women’s help-seeking behaviors. As such, this study aims to explore women survivors’ help-seeking behaviors in Kachin State, an ethnic area of Myanmar with an online in-depth interview approach. Twelve women survivors who were recruited by social workers, camp leaders, and volunteers participated in the study. Findings were analyzed by using the intimate partner violence help-seeking theory. In contrast to the extant literature, this study found an equal number of women survivors reached out to both formal and informal sources. Their help-seeking behaviors were influenced by their violence perception, cultural norms, lack of information on support services availability, the violence severity, and social support. Exposure to parental violence and women’s unique personal attributes had a negative impact on their decision to seek formal help. Results underscored the importance of sociocultural norms in an ethnic patriarchal society. As such, addressing deep-rooted patriarchal sociocultural norms, effective awareness raising, women’s empowerment, establishment of anti-domestic violence law, and multi-sectoral collaboration with men’s engagement and inclusion of cultural and religious leaders are urgently needed in ethnic communities to enhance formal help-seeking.

The crystal structure of the hydrated form of 7-chloro-4-(4-methyl-1-piperazinyl)quinoline (BPIP) was determined by single-crystal X-ray diffraction analysis. This study revealed a one-dimensional supramolecular network stabilized by hydrogen bonding interactions between BPIP and water molecules. This compound represents one-half of a piperaquine molecule, a member of the 4-aminoquinoline class of antimalarial treatments, currently employed as a partner agent in modern combination therapies. As a simplified structural analog, BPIP can serve as a critical model system for probing the intermolecular interactions, physicochemical properties, and structural behavior of the parent compound. As a result, conducting a thorough solid-state characterization of BPIP is critical for gaining insight into its physical properties and verifying the material’s identity and purity. Full article

Background: Intimate partner femicide (IPF) is the most common form of femicide and a severe expression of gender-based violence, highlighting persistent gender inequality worldwide. Addressing this major public health concern requires a comprehensive synthesis of existing evidence to inform prevention strategies. This review aims to identify risk factors for IPF and explore the demographic, behavioral, and psychosocial characteristics of victims and perpetrators. Methods: A narrative review was conducted using a systematic literature search in Scopus, Web of Science, and PubMed, following PRISMA guidelines. Studies were selected based on predefined inclusion and exclusion criteria. Out of 1200 identified records, 51 met the criteria and were included. Data extraction and analysis were conducted independently by two reviewers. Findings are presented narratively. Results: The review identified multiple risk factors for IPF. Victims were more likely to be married, with a history of psychological and physical abuse as well as substance use. Perpetrators were typically older, with higher rates of unemployment, psychiatric disorders, and substance use. Common precipitating factors included jealousy, separation, and recurrent conflicts. Weapon use—particularly knives and firearms—and “overkill” were frequent. Perpetrators often exhibited stalking behaviors and a history of intimate partner violence. Compared to other homicide offenders, IPF perpetrators were generally older, more often employed, and less likely to have a criminal background, but more likely to engage in intimate partner violence and hold patriarchal beliefs. Conclusions: IPF is not an unpredictable act. Despite the heterogeneity among perpetrators, identifiable risk indicators can inform effective prevention and intervention efforts. Full article

Background/Objectives: Cyber intimate partner violence (CIPV) in adolescents is influenced by individual and relational factors, including psychopathic traits, antisocial and law-violating behaviors, child-to-parent violence, and dating violence. This study examines predictors of cyber aggression, cyber control perpetration, cyber victimization, and received cyber control using hierarchical regression models (HRMs) and fuzzy-set Qualitative Comparative Analysis (fsQCA). Method: A total of 207 Spanish adolescents (M = 16.18; SD = 1.52) aged 14–18 years completed measures of psychopathy (P-16), antisocial behavior (ECADA), child-to-parent violence (CTS2), and dating violence (CADRI), together with Violence in Adolescent Relationships on Social Media (e-VPA). Results: HRM showed that child-to-parent violence and experienced dating violence were common predictors across cyber aggression, cyber victimization, and received cyber control. Cyber control perpetration was mainly influenced by psychopathy and perpetrated dating violence. fsQCA revealed multiple pathways leading to high levels of CIPV, combining psychopathy, antisocial behaviors, and family and partner violence. However, cyber aggression perpetration could not be analyzed due to insufficient variability. Conclusions: The findings suggest that CIPV might stem from complex interactions between individual traits and offline relational violence. Prevention efforts should address both family dynamics and dating violence to mitigate cyber aggression and victimization in adolescent relationships. Full article

The rapid emergence of the platform economy has accelerated the practice of embedded innovation, with ecosystem partner selection serving as a critical first step in platform enterprises’ innovation collaborations and playing a key role in enhancing innovation efficiency and outcomes. Based on the theory of embedded innovation, this study identifies the core innovation demands of platform enterprises at distinct stages. It then employs QFD to quantify decision indicator weights for ecosystem partner selection. By integrating Prospect Theory with Field Theory, this study develops both a decision evaluation model and an optimization model to achieve the optimal screening of ecosystem partners. Specifically, this study contributes in the following ways: (1) It constructs an embedded innovation direction selection model to uncover the evolving innovation demands at each stage. Within the QFD framework, we map these demands onto selection evaluation indicators, assess their importance via the maximum entropy principle, and determine indicator weights through a correlation matrix. (2) It proposes a Prospect Theory-based TOPSIS evaluation model, incorporating decision-makers’ psychological preferences to mitigate bias arising from singular or excessive risk attitudes. This model ranks potential partners according to their closeness to an ideal solution. Finally, (3) it designs a Field Theory-based optimization model that accounts for the platform enterprise’s perspective, partner-matching rationality, and continuity of interaction. This model emphasizes the complementarity and synergy of innovation resources to enhance cooperation fit and strategic alignment between the platform and its partners. Finally, this study conducts an empirical analysis on platform enterprise XM and validates the model’s feasibility and stability through sensitivity testing and comparative analyses. This study enriches the understanding of ecosystem partner selection within platform ecosystems by advancing methods for quantifying partner demands and refining the selection of evaluation indicators. It also deepens the depiction of non-rational characteristics in behavioral decision-making and elucidates the mechanisms underlying the ongoing interactions between platform enterprises and their ecosystem partners. These theoretical contributions not only extend the scope of research on platform ecosystems and embedded innovation but also provide feasible approaches for platform enterprises to improve partner governance and foster collaborative innovation in dynamic and complex environments. Ultimately, the findings offer strong support for enhancing innovation performance and building sustainable competitive advantages. Full article
