Revival of Degraded CsPbI3 Nanocrystals by Diselenide Ligand and Nanocrystal Self-Assembly on Nanofibrilar Ligand Template.

Among the lead halide perovskite (LHP) family, CsPbI3 is known to be significantly vulnerable to moisture, which hinders its use in real device applications. It is reported that chalcogen-based ligands can better stabilize CsPbI3 and revive nanocrystals (NCs). Here, diphenyl diselenide (DPhDSe) ligand is used to revive the degraded CsPbI3 NCs through a post-synthetic treatment of adding a small amount of DPhDSe in the degraded NC dispersion. DPhDSe in the dispersion formed nanofibrillar crystals at a low temperature through the π-π stacking of the phenyl ring. The nanofibrils played as a template on which the NCs self-assembled and they are attached side-by-side to form microfibers. The microfiber powder containing the NCs is optically stable at ambient conditions and morphologically self-healable by mild thermal annealing due to the dynamic Se─Se bond. The mechanism of the structural changes, optical transitions, and chemical changes has been systematically characterized through electron microscopy, diffraction, spectroscopy, and elemental analysis.

Friendship Homophily Trajectories among Asian American Youth from High School to College.

Friendship racial homophily, the tendency to form friendships with individuals who share the same racial background, is a normative developmental phenomenon that holds particular significance for youth of color in a racialized society. Yet, there exists a paucity of longitudinal research elucidating the stability and change of friendship racial composition across developmental span. This study aimed to examine the friendship racial homophily trajectories over a six-year period encompassing four time points. The sample comprised 437 Asian American youth (MAge = 16.52, SDAge = 1.36, 53% female), with 197 Filipino and 240 Korean participants. Using logistic multilevel modeling analyses, it was found that both Filipino and Korean American youth demonstrated an increase in friendship racial homophily from high school to college, but that Filipino youth overall reported lower levels of racial homophily compared to their Korean counterparts. The study findings also pinpointed several influential factors impacting these trajectories, including proficiency in heritage languages, ethnic identity, and encounters with racial discrimination from both White Americans and other People of Color. These results highlight the continuous evolution of friendship racial composition from high school to college and emphasize the crucial role of ethnic identity and experiences of discrimination in influencing these dynamics, with ethnic identity exerting more enduring effects and experiences of discrimination showing more situational impacts on the levels of racial homophily.

Parental Academic Socialization and Youth Adjustments: A Comparison of Korean Youth in South Korea, China, and the United States.

Although parental academic socialization may be a product of culture, ethnic/racial minority status may play a significant role, above and beyond the impact of culture, in shaping parental academic socialization and its implications for youth adjustments. This study examined Korean youth living in South Korea (N = 524, Mage = 14.98, SD = 1.45, 50.1% female), China (N = 267, Mage = 15.24, SD = 1.66, 58.9% female), and the U.S. (N = 408, Mage = 14.76, SD = 1.91, 47.3% female) who share the same heritage culture but have different social positions (majority or minority). Korean youth as an ethnic/racial minority in the U.S. or China reported higher parental academic socialization than those in South Korea, supporting a significant role of social positions in how parents practice academic socialization. This study also found that the distinct practices of academic socialization function differently in youth adjustment. Parental commitment to education, parental involvement, and autonomy support were positively associated with youth's school engagement, but achievement-oriented psychological control was associated with more depressive symptoms and antisocial behaviors. These associations did not differ across the three samples. Some nuanced differences also emerged. Parental commitment to education was associated with higher grades in Korean Chinese (but not Korean American) youth, and achievement-oriented psychological control was associated with lower school engagement among Korean Chinese (but not South Korean) youth and higher grades among South Korean (but not Korean American) youth. These findings highlight the role of academic socialization as an adaptive strategy for ethnic/racial minorities to succeed in host societies and the generally universal role of parental academic socialization in youth adjustments.

Cultural family processes, depressive symptoms, and suicidal ideation: A longitudinal study of Asian American youths.

INTRODUCTION: This prospective study examined the direct and interactive effects of depressive symptoms and cultural family processes (i.e., intergenerational cultural conflict, academic parental control, cultural socialization parenting) on Asian American youths' suicidal ideation from adolescence to young adulthood. METHODS: We utilized three-wave data of 408 Korean American and 378 Filipino American youths (M = 15.00 years, SD = 1.91 at Wave 1). For each ethnicity, we tested (1) whether depressive symptoms and cultural family processes predicted past-year suicidal ideation; and (2) whether cultural family processes moderated the depressive symptom-suicidal ideation link. RESULTS: Across ethnicities, depressive symptoms significantly predicted suicidal ideation after controlling for cultural family processes. For Filipino youths, intergenerational cultural conflict significantly predicted suicidal ideation after controlling depressive symptoms and exacerbated the depressive symptom-suicidal ideation link. For Filipino youths, depressive symptoms were significantly associated with suicidal ideation only at lower levels of cultural socialization parenting. For Korean youths, academic parental control exacerbated the depressive symptom-suicidal ideation link. CONCLUSION: Findings suggest that while depressive symptoms have a robust effect on Asian American youths' suicidal ideation, this effect may be moderated by cultural family processes. Different findings for Korean and Filipino youths highlight the importance of disaggregating analyses by ethnicity to guide prevention efforts.

Acculturation/enculturation and internalized model minority myth in Korean immigrant families.

Drawing on Bronfenbrenner's ecological systems theory (1977), this study examined the antecedents and outcomes of internalized model minority myth (MMM) within the microsystem of family and the macrosystem of culture. Among Korean immigrant families, we examined how mothers' internalized MMM (i.e., achievement orientation, unrestricted mobility) and youth's cultural orientations (i.e., acculturation, enculturation) were related to youth's internalized MMM and had direct and indirect relations to youth outcomes (i.e., life satisfaction, depression, antisocial behaviors, and academic performance). In a sample of 334 Korean immigrant mother-youth dyads (155 female youth; 132 foreign-born youth; Mage of youth = 16.37; Mage of mothers = 46.94), we conducted a path analysis by using the maximum likelihood and bootstrapping methods. A path analysis revealed mothers' achievement orientation was indirectly related to youth's academic performance via youth's beliefs in unrestricted mobility. In general, mothers' internalized MMM had harmful relationships to youth's depression and antisocial behaviors versus mixed relationships to academic performance. Importantly, mothers' internalized MMM indicated greater direct and indirect associations with youth outcomes than youth's own internalized MMM. A follow-up analysis of moderated mediation ruled out the possibility that academic performance moderated the relations of youth's internalized MMM and outcomes and thus masked any significant associations. Overall, the current findings highlighted the importance of understanding the internalized MMM within the microsystem of the close-knit Korean immigrant family relations. Implications for research, family intervention, parent education and outreach were discussed.

Correlates of Stigma Toward Mental Health Service Use Among Filipino Americans and Korean Americans.

Asian Americans are less likely than Whites to seek mental care and when they do, there is a substantial delay in help-seeking. Stigma associated with mental health service use is one of the major barriers to help-seeking among Asian Americans. However, few studies have examined multi-layered contextual predictors of stigma to examine joint as well as unique contributions of each predictor. Using a cross-sectional study of 376 Filipino and 412 Korean American parents from the Midwestern U.S., we investigated how individual, familial, ethnic cultural, and macro level factors were associated with stigma among immigrant parents. The findings from hierarchical regressions suggest that familial and ethnic cultural factors are prominent predictors of stigma among Korean Americans, whereas macro level factors are particularly pertinent to Filipino Americans. This study highlights the significance of subgroup specific interventions to be effective in addressing unmet mental care needs in distinct subgroups of Asian Americans.

Parental socialization of mental health in Chinese American families: What parents say and do, and how youth make meaning.

Parental mental health socialization is a process by which parents shape how youth develop and maintain beliefs, attitudes, and behaviors regarding mental health and help-seeking behaviors. Although culture shapes parental mental health socialization, few studies have examined specific parental socialization practices regarding mental health and help-seeking, especially as a culturally anchored process. Using a qualitative approach, this study explores youth-reported parental socialization of mental health within Chinese American families by examining focus group data from 69 Chinese American high school and college students. Findings revealed that youth received parental messages that conveyed culturally anchored conceptualizations of mental health that included stigmatized views of mental illness and perceptions of mental distress as not a legitimate problem. Parents responded to youth distress in culturally consonant ways: by encouraging culturally specific coping methods, dismissing or minimizing distress, or responding with silence. Youth engaged in the active interpretation of parental messages through cultural brokering, bridging the gap between their parents' messages and mainstream notions of mental health and help-seeking. Overall, our findings point to the significant role of culture in parental mental health socialization in Chinese American families and the need to integrate culturally specific understandings of mental health into future interventions for Asian American youth.

New Approaches to Produce Large-Area Single Crystal Thin Films.

Wafer-scale growth of single crystal thin films of metals, semiconductors, and insulators is crucial for manufacturing high-performance electronic and optical devices, but still challenging from both scientific and industrial perspectives. Recently, unconventional advanced synthetic approaches have been attempted and have made remarkable progress in diversifying the species of producible single crystal thin films. This review introduces several new synthetic approaches to produce large-area single crystal thin films of various materials according to the concepts and principles.

Ethnic-Racial Socialization, Ethnic-Racial Identity, and Depressive Symptoms in Korean Adolescents in the United States and China.

The United States and China are top two receiving countries of Korean immigrants in modern history. Minority families in ethnically-racially diverse societies, such as the US and China, use various ethnic-racial socialization practices (cultural socialization, promotion of mistrust, preparation for bias) to help their children navigate the world, yet research in non-U.S. contexts is scarce. To examine the specificity versus generalizability of ethnic-racial socialization and its implications, this study compared the prevalence of ethnic-racial socialization reported by Korean American (n = 408; Mage = 14.76, SD = 1.91; 48.30% female) and Korean Chinese (n = 267; Mage = 15.24, SD = 1.66; 58.90% female) youth. Moreover, this study examined how various ethnic-racial socialization practices relate to the youth's ethnic-racial identity, and subsequently, depressive symptoms. Although Korean American youth reported more frequent ethnic-racial socialization compared to their Korean Chinese counterparts, cultural socialization (but not preparation for bias nor promotion of mistrust) had a comparable negative indirect association with depressive symptoms via ethnic-racial identity across both groups. Thus, although the rates of parental ethnic-racial socialization are context-specific, parental cultural socialization may be similarly beneficial for Korean ethnic-racial minority youth's identity development, and in turn, psychological outcomes, whether in a Western individualistic society or an Eastern collectivistic society.

Upholding Familism Among Asian American Youth: Measures of Familism among Filipino and Korean American Youth.

Although it is one of the core cultural values of Asian American families and an influential determinant of youth development, familism remains under-studied among Asian Americans and, despite crucial within-group heterogeneity, lacks subgroup specificity. This study describes the ways in which two major Asian American subgroups of youth, i.e., Filipino Americans and Korean Americans, maintain traditional familism. Specifically, this study constructed six self-report subscales of familism utilizing underused and new survey items and tested their psychometric properties. Using data collected from Filipino American (n=150) and Korean American (n=188) adolescents living in a Midwest metropolitan area, the measures were examined for validity and reliability for each group and, when appropriate, for measurement invariance across the groups. The main findings are that the finalized scales demonstrated solid reliability and validity (e.g., content and construct) in each group and some invariance and that core traditions, in the form of familism values and behaviors, persevere among second-generation Asian Americans, although familism was more evident among Filipino American youth than in Korean American youth. In both groups, subdomains of familism were not as discrete as found among their parents, who were predominantly foreign-born first-generation immigrants. The finalized familism scales were associated differently with several correlates including acculturation variables and youth outcomes. The findings are discussed with a call for further empirical research of diverse ethnic groups and immigrant generations to more accurately account for how family process interacts with cultural origin and acculturation.

Racial Stereotypes and Asian American Youth Paradox.

Asian Americans are simultaneously stereotyped as a perpetual foreigner and a model minority. This cross-sectional study of 308 Filipino American youth (mean age 18 years; 47% emerging adult; 72% U.S.-born; 57% female) and 340 Korean American youth (mean age 18 years; 39% emerging adult; 59% U.S.-born; 49% female) is the first to investigate both the direct and interactive effects of these seemingly opposite stereotypes on internalizing and externalizing outcomes, and how these relations differ by ethnicity, age group (adolescence vs. emerging adulthood), and nativity (foreign-born vs. U.S.-born). The results confirm that the perpetual foreigner stereotype predicts more internalizing problems, whereas aspects of the model minority stereotype (i.e., achievement orientation and unrestricted mobility) had different effects by ethnicity. Those who deeply internalize the model minority stereotype were found to be particularly vulnerable. Furthermore, the interactive effects of these stereotypes were more prominent during emerging adulthood than in adolescence, regardless of ethnicity. These nuanced and complex mechanisms need to be thoroughly understood in order to develop appropriate and effective public health or school interventions that can support Asian American young people in dealing with the harmful effects of racial stereotypes.

Racial discrimination and the moderating effects of racial and ethnic socialization on the mental health of Asian American youth.

This study investigates trajectories of racial discrimination, racial and ethnic socialization (RES), and their interaction effects with social positions (nativity and gender) on mental health. A longitudinal study of 786 Filipino American (FA) and Korean American (KA) youth from the Midwestern United States (Mage.Wave1  = 15) confirmed that discrimination increased and significantly contributed to the upward trend of mental health distress, whereas the impact of RES differed by its type and by ethnicity. For example, promotion of mistrust and ethnic-heritage socialization were protective among U.S.-born FA youth, but for KA youth, preparation for bias was protective regardless of nativity and gender. This study highlights the importance of considering social positions to better understand the role of RES in youth psychological adjustment.

Examination of Korean immigrant mothers' parenting practices: By using the framework of bilinear acculturation.

By using the conceptual framework of bilinear acculturation, this study examined Korean immigrant mothers' parenting practices among 389 mother-youth (adolescent children in middle or high school) dyads. We examined (a) how mothers' acculturation and enculturation were related to mainstream (i.e., authoritarian vs. authoritative styles, communication, warmth/bonding, autonomy support) versus culture specific parenting practices (i.e., interdependence, commitment to education, academic control) and (b) how parenting practices were, in turn, linked to youth outcomes of depression, antisocial behaviors, and academic performance as measured 1.5 years later. Mothers and youth had significant perceptual gaps in parenting practices, especially in autonomy support and parental commitment to education. Therefore, path analyses were conducted separately for mother-reported versus youth-reported parenting. As hypothesized, mothers' acculturation was more closely related to mainstream parenting, while enculturation was to culture specific parenting. Mother-reported autonomy support predicted higher academic performance, while youth-reported authoritarian parenting predicted lower academic performance. Youth-reported communication predicted lower depression and antisocial behaviors. The current findings have implications for parenting and family interventions to optimize Korean immigrant youth's wellbeing in the bicultural context. Additionally, bilinear acculturation was found to be a useful conceptual framework in studying immigrant parenting.

Automotive augmented reality 3D head-up display based on light-field rendering with eye-tracking.

We explore the feasibility of implementing stereoscopy-based 3D images with an eye-tracking-based light-field display and actual head-up display optics for automotive applications. We translate the driver's eye position into the virtual eyebox plane via a "light-weight" equation to replace the actual optics with an effective lens model, and we implement a light-field rendering algorithm using the model-processed eye-tracking data. Furthermore, our experimental results with a prototype closely match our ray-tracing simulations in terms of designed viewing conditions and low-crosstalk margin width. The prototype successfully delivers virtual images with a field of view of 10° × 5° and static crosstalk of <1.5%.

Disempowering Parenting and Mental Health among Asian American Youth: Immigration and Ethnicity.

Guided by the concept of ABCDG (Abusive, Burdening, Culturally Disjointed, Disengaged, and Gender Prescriptive) parenting, this study investigated how subdomains of disempowering parenting adversely influence young people's mental health, independently and collectively, using a large-scale longitudinal survey data of community samples among Filipino American (FA) and Korean American (KA) youth (M AGE =15.01, N=1,580; 391 FA and 417 KA families). Regression results showed that the subdomains of disempowering parenting, while individually harmful, were differentially associated with mental health. For example, abusive and disengaged parenting and culturally disjointed parenting (a.k.a. intergenerational cultural conflict) were the most notably adverse subdomains and remained significant when all subdomains were accounted together. This study pinpoints specific aspects of disempowering parenting that may lead to mental distress among FA and KA youth and underscores a need for culturally tailored intervention programs that address the harms of disempowering parenting approaches.

Development and in-vitro evaluation of co-loaded berberine chloride and evodiamine ethosomes for treatment of melanoma.

Berberine chloride (BBR) and evodiamine (EVO) are two main active ingredients of "ZuoJinWan", a classical Chinese herbal medicine, and these compounds are known to have a synergistic inhibitory effect on various cancer cell lines. Several recent studies have reported anti-melanoma effects for both BBR and EVO. However, topical delivery of the two compounds has been challenging, due to their poor aqueous solubility and their low skin penetration. In the current study, we have combined BBR and EVO into an ethosomes delivery system with the future aim to design a novel topical anti-melanoma formulation. The ethosomes formulations were characterized using particle size, entrapment efficiency and an in vitro skin drug deposition study. The ethosome formulation displaying maximum drug deposition in the epidermis was selected for further study. This formulation contained ethosomes with mean size of 171 nm and 90% or above entrapment efficiency for both BBR and EVO. Cell viability tests proved the optimized ethosomes increased the inhibitory effect on B16 melanoma cells. These results corroborate that ethosomes containing a combination of BBR and EVO are a promising delivery system for potential use in melanoma therapy.

Explaining the Asian American Youth Paradox: Universal Factors versus Asian American Family Process Among Filipino and Korean American Youth.

This study used longitudinal survey data of Filipino American and Korean American youth to examine ways in which universal factors (e.g., peer antisocial behaviors and parent-child conflict) and Asian American (AA) family process variables (e.g., gendered norms) independently and collectively predict grade point average (GPA), externalizing, and internalizing problems. We aimed to explain the "Asian American youth paradox" in which low externalizing problems and high GPA coexist with high internalizing problems. We found that universal factors were extensively predictive of youth problems and remained robust when AA family process was accounted for. AA family process also independently explained youth development and, in part, the AA youth paradox. For example, gendered norms increased mental distress. Academic controls did the opposite of what it is intended, that is, had a negative impact on GPA as well as other developmental domains. Family obligation, assessed by family-centered activities and helping out, was beneficial to both externalizing and internalizing youth outcomes. Parental implicit affection, one of the distinct traits of AA parenting, was beneficial, particularly for GPA. This study provided important empirical evidence that can guide cross-cultural parenting and meaningfully inform intervention programs for AA youth.

Este estudio utilizó datos de una encuesta longitudinal de jóvenes filipinoamericanos y coreanoamericanos para analizar las maneras en las que los factores universales (p. ej.:las conductas antisociales entre pares y el conflicto entre padres e hijos) y las variables de los procesos familiares asiáticoamericanos (p. ej.: las normas de género) predicen independientemente y colectivamente el promedio de calificaciones y los problemas interiorizados y exteriorizados. Nos propusimos explicar la "paradoja de los jóvenes asiáticoamericanos" en la cual un bajo grado de problemas exteriorizados y un alto promedio de calificaciones coexisten con un alto grado de problemas interiorizados. Descubrimos que los factores universales fueron en gran parte predictivos de los problemas de los jóvenes y se mantuvieron firmes cuando se tuvo en cuenta el proceso familiar asiáticoamericano. El proceso familiar asiáticoamericano también explicó independientemente el desarrollo de los jóvenes y, en parte, la paradoja de los jóvenes asiáticoamericanos. Por ejemplo, las normas de género aumentaron el distrés mental. Los controles académicos hicieron lo opuesto a lo deseado, por ejemplo, tuvieron un efecto negativo en el promedio de calificaciones así como en otras áreas del desarrollo. La obligación familiar, evaluada por actividades centradas en la familia y por la colaboración, fue beneficiosa tanto para los resultados exteriorizados como interiorizados de los jóvenes. El afecto implícito de los padres, uno de los rasgos distintivos de la crianza de los asiáticoamericanos, fue beneficioso, particularmente para el promedio de calificaciones. Este estudio ofreció importante conocimiento empírico que puede guiar la crianza intercultural y respaldar de manera significativa programas de intervención para jóvenes asiáticoamericanos.

Racial discrimination, ethnic-racial socialization, and cultural identities among Asian American youths.

OBJECTIVES: This study investigates whether and how racial discrimination is associated with ethnic-racial socialization in the family and how distinct aspects of ethnic-racial socialization influence children's ethnic and American identity among Filipino American and Korean American families. METHOD: The data are obtained from the Midwest Longitudinal Study of Asian American Families Project (N = 1,580; 379 Filipino American youths and 377 parents, and 410 Korean American youths and 414 parents; Mage of youths = 15.01). Using the bootstrapping and maximum likelihood with missing values approaches, we conducted path analyses to test the hypothesized associations concurrently and longitudinally for each ethnic group. RESULTS: Youth-reported racial discrimination was directly associated with weaker American identity, both concurrently and longitudinally. In concurrent models, racial discrimination experienced by both youth and parents was positively associated with youth-reported preparation for bias, which in turn was linked with stronger ethnic identity among Filipinos, whereas no indirect pathways reached statistical significance among Koreans. In longitudinal models, parent-reported discrimination was linked with higher levels of promotion of mistrust among both groups, which predicted weaker ethnic identity among Filipino youth but stronger American identity among Korean youth. CONCLUSIONS: The present study highlights how exposure to racial discrimination may have a lasting influence in cultural identity development among Asian Americans and possibly through ethnic-racial socialization in the family, which might have been shaped by such experiences. Our results also underscore the importance of considering the experiences of both children and parents in studies of discrimination and ethnic-racial socialization.

Asian American mental health: Longitudinal trend and explanatory factors among young Filipino- and Korean Americans.

OBJECTIVES: This study examined a longitudinal trend of mental health among young Asian Americans during the transition from adolescence to emerging adulthood and investigated explanatory factors of the trend. METHOD: We longitudinally followed a cohort of Filipino American and Korean American youth and their families in Midwest since 2014 (N = 1,574 in Wave 1). This study used three waves of youth data (n = 781, M AGE  = 15 in W1). RESULTS: Depressive symptoms and suicidal ideation significantly increased among the samples between 2014 and 2018, which also became more serious in severity. Intergenerational cultural conflict in the family and the experience of racial discrimination significantly contributed to the upsurge of mental health distress. Conversely, a strong peer relationship and ethnic identity were critical resources suppressing both depressive symptoms and suicidal ideation. CONCLUSIONS: This study substantiated a troubling upward trend in mental health struggles among young Asian Americans and demonstrated a significant additive influence of culture and race/ethnicity on mental health beyond the normative influences of family process and peers. These key factors should be targeted in intervention to better serve Asian American young people who may mask their internal struggles.

Cultural Orientation and Psychosocial Adjustment Among Immigrant Adolescents in South Korea.

The present study primarily uses Berry's theoretical model to examine national identity, acculturation (to South Korea), ethnic identity, and enculturation (to country-of-origin), and how they are linked to immigrant adolescents' aggression and depression in South Korea. Data were collected from 120 immigrant youths (i.e., those born in South Korea and those born in their country-of-origin) in eight middle schools. Analyses include multivariate regression and cluster analyses. Findings indicate that South Korean identity (m = 48, F = 77.0, p < .001), acculturation to South Korean culture (m = 44.9, F = 52.3, p < .01), and mother's Korean proficiency (m = 3.6, F = 10.9, p < .001) were higher among Korea-born adolescents. Enculturation (m = 35.5, F = 13.7, p < .001) and depression (m = 36.4, F = 15.3, p < .001) were higher among foreign-born adolescents. Aggression (r = - .26, p < .01) and depression (r = - .46, p < .01) were lower among native-born Korean adolescents. South Korean identity (B = - .27, p = .02) and acculturation (B = - .28, p = .01) were negatively associated with aggression. South Korean identity (B = - .22, p = .04), acculturation (B = - .21, p = .03), and ethnic identity (B = - .17, p = .02) were negatively associated with depression. Integration youth (M = 12.7) and assimilation youth (M = 11.5) reported lower aggression than marginalization youth (M = 15.8, F = 5.48, p < .01). Assimilation type had better outcomes than separation and marginalization types.
