Introduction: The global market of flavour capsule cigarettes (FCCs) has grown significantly over the past decade; however, prevalence data exist for only a few countries. This study examined prevalence and perceptions of FCCs among adults who smoke across five countries., Methods: Cross-sectional data among adults who smoked cigarettes came from the International Tobacco Control Policy Evaluation Project Surveys-Brazil (2016/2017), Japan (2021), Republic of Korea (2021), Malaysia (2020) and Mexico (2021). FCCs use was measured based on reporting one's usual/current brand or favourite variety has flavour capsule(s). Perceptions of the harmfulness of one's usual brand versus other brands were compared between those who used capsules versus no capsules. Adjusted logistic regression models examined correlates of FCC use., Results: There were substantial differences in the prevalence of FCC use among adults who smoke across the five countries: Mexico (50.3% in 2021), Republic of Korea (31.8% in 2021), Malaysia (26.5% in 2020), Japan (21.6% in 2021) and Brazil (6.7% in 2016/2017). Correlates of FCC use varied across countries. Capsule use was positively associated with being female in Japan and Mexico, younger age in Japan, Republic of Korea and Malaysia, high education in Brazil, Japan and Mexico, non-daily smoking in Republic of Korea, and having plans to quit in Japan and Republic of Korea. There was no consistent pattern of consumer perceptions of brand harmfulness., Conclusion: Our study documented the high prevalence of FCCs in some countries, pointing to the need to develop and implement regulatory strategies to control these attractive products., Competing Interests: Competing interests: JFT has served as paid expert witness in legal challenges against tobacco and vaping companies.

Mothers and adolescents often perceive parenting differently, but it is unclear how different profiles of mother-adolescent perceived parenting and developmental transitions of such profiles would influence adolescent academic performance longitudinally. The current study adopted a three-wave dataset of 604 Mexican-origin adolescents (54% female; M wave1.age  = 12.92 years) and 595 mothers. Adolescents who agreed on high levels of positive parenting with their mothers in early adolescence (i.e., the Both High group) and stayed in the Both High group demonstrated the best academic performance in late adolescence. However, adolescents who changed from the Both High group in early adolescence and ended with discrepancies in perceived parenting or an agreement on low positive parenting with mothers in late adolescence had the worst academic performance. The findings suggest the plasticity of mother-adolescent relationships during adolescence, which can be an intervention target to improve Mexican-origin adolescent academic performance., (© 2022.

Although Mexican-origin youth with first-generation immigrant parents are relatively good at retaining their heritage language of Spanish, limited research has been conducted on their Spanish language development during adolescence. From three-wave longitudinal data across six years (N wave1  = 604, M age.wave1  = 12.91, 54% female), distinct groups of adolescents with consistently high, improved, declined, and consistently low Spanish proficiencies were identified. Family relationship quality was more predictive of adolescents' Spanish proficiency than family language environment. The benefits of Spanish proficiency were consistent across adolescents' ethnic identity, resilience, and life meaning. More research and practical attention to parent-adolescent relationships is needed to capitalize on the continued plasticity of adolescents' Spanish language development and to promote consequent positive outcomes., (© 2022.

The intergenerational transmission of executive function may be enhanced or interrupted by culturally salient environmental stressors that shape the practice of executive function in the family. Building upon past research, the current study tests whether culturally relevant stressors such as economic stress and foreigner stress have a direct effect on adolescent executive function, as well as whether they modify the intergenerational transmission of mother-child executive function (i.e., working memory, inhibitory control, and shifting) in low-income Mexican immigrant families. The sample consists of 179 Mexican American adolescents (M age  = 17.03 years; SD age  = 0.83; 58% females) and their Mexico-born mothers (M age  = 43.25 years; SD age  = 5.90). Results show that mothers' perceived economic stress is associated with poor inhibitory control in adolescents. Low levels of mothers' perceived foreigner stress related to a stronger association between mothers' and adolescents' working memory, while high levels of mothers' perceived foreigner stress related to enhanced intergenerational transmission of poor shifting ability. Study findings demonstrate the prominence of perceived foreigner stress as a contextually relevant factor moderating the intergenerational transmission of mother-child executive function in low-income Mexican immigrant families., (© 2021.

Prior studies investigating the association between acculturation and adolescent adjustment have often focused on specific acculturation domains rather than examining these domains collectively in a profile typology. Here, we investigate stability and change patterns in Mexican American adolescent acculturation profiles over time, using a two-wave longitudinal dataset spanning 5 years. Using latent profile analysis, three adolescent acculturation profiles were identified at Waves 1 and 2: integrated; moderately integrated; and moderately assimilated. Using latent transition analysis, four acculturation transition profiles were identified across time: stable integrated; stable moderately integrated; progressive; and regressive. Over half of all adolescents were identified as belonging to the stable integrated and stable moderately integrated transition profiles. Adolescents classified in the stable integrated profile reported the highest levels of adjustment (academic competence and socioemotional well-being) relative to those with other transition profiles. Findings from this study contribute to a comprehensive understanding of the dynamic process of acculturation among Mexican American adolescents, and provide useful insights to inform interventions and policies aimed at improving Mexican-origin adolescents' adaption to US culture while maintaining their heritage Mexican culture., (© 2021 Wiley Periodicals LLC.)

We advance a tripartite framework of language use to encompass language skills, the practice of language skills, and the subjective experiences associated with language use among Mexican-origin adolescents who function as language brokers by translating and interpreting for their English-limited parents. Using data collected over 2 waves from a sample of 604 adolescents (Wave 1: Mage = 12.41, SD = 0.97), this study identified 4 types of bilingual language broker profiles that capture the tripartite framework of language use: efficacious, moderate, ambivalent, and nonchalant. All 4 profiles emerged across waves and brokering recipients (i.e., mothers, fathers), except for Wave 1 brokering for mother, in which case only 3 profiles (i.e., efficacious, moderate, and ambivalent) emerged. Three profiles emerged across time: stable efficacious, stable moderate, and other. The efficacious and stable efficacious profiles showed the most consistent relation to adolescents' academic competence. Improving bilingual language proficiency, together with fostering more frequently positive brokering experiences, may be an avenue to improving academic competence among Mexican-origin adolescents in the United States.

Objectives: Recognizing that immigrant parents socialize their children in specific ways, the current study examines Mexican-origin families' parental socialization profiles using both parental cultural socialization and general parenting dimensions. We seek to understand how these dimensions interact to form culturally grounded parental socialization profiles in a sample of Mexican-origin parents and adolescents., Method: There were 604 adolescents, 595 mothers, and 293 fathers within Mexican-origin families self-reporting on 2 cultural socialization dimensions (respeto, independence) and 4 general parenting dimensions (warmth, hostility, monitoring, reasoning). Adolescent outcomes were assessed 1 year later., Results: Latent profile analysis revealed eight parental socialization profiles representing distinct combinations of cultural socialization and parenting dimensions. Relative to other profiles, the Integrative-Authoritative profile (high on socialization toward respeto and independence; high on warmth, monitoring, and reasoning; and relatively low on hostility) was the most common parenting pattern and was also associated with more optimal adolescent outcomes., Conclusion: Examining cultural socialization alongside general parenting dimensions can better capture parental socialization strategies among Mexican-origin parents. The various parental socialization profiles that characterize Mexican-origin parents have important implications for adolescent outcomes.

Theories of ageing predict that early reproduction should be associated with accelerated reproductive senescence and reduced longevity. Here, the influence of age of first reproduction on reproductive senescence and lifespan, and consequences for lifetime reproductive success (LRS), were examined using longitudinal reproductive records of male and female blue-footed boobies (Sula nebouxii) from two cohorts (1989 and 1991). The two sexes showed different relationships between age of first reproduction and rate of senescent decline: the earlier males recruited, the faster they experienced senescence in brood size and breeding success, whereas in females, recruiting age was unrelated to age-specific patterns of reproductive performance. Effects of recruiting age on lifespan, number of reproductive events and LRS were cohort- and/or sex-specific. Late-recruiting males of the 1989 cohort lived longer but performed as well over the lifetime as early recruits, suggesting the existence of a trade-off between early recruitment and long lifespan. In males of the 1991 cohort and females of both cohorts, recruiting age was apparently unrelated to lifespan, but early recruits reproduced more frequently and fledged more chicks over their lifetime than late recruits. Male boobies may be more likely than females to incur long-term costs of early reproduction, such as early reproductive senescence and diminished lifespan, because they probably invest more heavily than females. In the 1991 cohort, which faced the severe environmental challenge of an El Niño event in the first year of life, life-history trade-offs of males may have been masked by effects of individual quality.

The San Diego/Tijuana border region has several environmental challenges with regard to assessing water quality impacts resulting from local coastal ocean discharges for which transport is not hindered by political boundaries. While an understanding of the fate and transport of these discharged plumes has a broad audience, the spatial and temporal scales of the physical processes present numerous challenges in conducting assessment with any fidelity. To address these needs, a data-driven model of the transport of both shoreline and offshore discharges is developed and operated in a hindcast mode for a four-year period to analyze regional connectivity between the discharges and the receiving of waters and the coastline. The plume exposure hindcast model is driven by surface current data generated by a network of high-frequency radars. Observations provided by both boat-based CTD measurements and fixed oceanographic moorings are used with the Roberts-Snyder-Baumgartner model to predict the plume rise height. The surface transport model outputs are compared with shoreline samples of fecal indicator bacteria (FIB), and the skill of the model to assess low water quality is evaluated using receiver operating characteristic (ROC) analysis.

This study of 598 7th grade students of Mexican origin examined the role of traditional cultural values as a mediator of the effects of immigrant status, Mexican cultural orientation and Anglo cultural orientation on adolescent externalizing behavior and academic engagement. Immigrant status of adolescents and their maternal caregivers uniquely predicted increased Mexican cultural orientation and decreased Anglo cultural orientation, and both Mexican and Anglo cultural orientation related positively to adolescents' endorsement of traditional cultural values. Endorsement of traditional cultural values related, in turn, to decreased externalizing behaviors and increased academic engagement and these findings were replicated across adolescent and teacher report of these two outcomes. Tests of mediation provided further evidence to support these pathways. Findings support the central importance of traditional cultural values as a protective resource that explains why immigrant youth exhibit fewer externalizing problems and increased academic engagement when compared to their second and third generation peers.
