Work and Mexican American Parent-Adolescent Relationships: The Mediating Role of Parent Well-Being

This study of Mexican American two-parent families (N = 246) examined the role of parents’ well-being (i.e., depressive symptoms, role overload) as a potential mechanism through which parent occupational conditions (i.e., self-direction, hazardous conditions, physical activity, work pressure) are linked to parent-adolescent relationship qualities (i.e., warmth, conflict, disclosure). Depressive symptoms mediated the links between maternal and paternal work pressure and parentadolescent warmth, conflict, and disclosure. For mothers, depressive symptoms also mediated the links between self-direction and mother-adolescent warmth, conflict, and disclosure; for fathers, role overload mediated the links between work pressure and hazardous conditions with fatheradolescent warmth

Mexican-Origin Parents’ Work Conditions and Adolescents’ Adjustment

Mexican-origin parents’ work experiences are a distal extra-familial context for adolescents’ adjustment. This two-wave multi-informant study examined the prospective mechanisms linking parents’ work conditions (i.e., self-direction, work pressure, workplace discrimination) to adolescents’ adjustment (i.e., educational expectations, depressive symptoms, risky behavior) across the transition to high school drawing on work socialization and spillover models. We examined the indirect effects of parental work conditions on adolescent adjustment through parents’ psychological functioning (i.e., depressive symptoms, role overload) and aspects of the parent-adolescent relationship (i.e., parental solicitation, parent-adolescent conflict), as well as moderation by adolescent gender. Participants were 246 predominantly immigrant, Mexican-origin, two-parent families who participated in home interviews when adolescents were approximately 13 and 15 years of age. Results supported the positive impact of fathers’ occupational self-direction on all three aspects of adolescents’ adjustment through decreased father-adolescent conflict, after controlling for family socioeconomic status and earner status, and underemployment. Parental work pressure and discrimination were indirectly linked to adolescents’ adjustment, with different mechanisms emerging for mothers and fathers. Adolescents’ gender moderated the associations between fathers’ self-direction and girls’ depressive symptoms, and fathers’ experiences of discrimination and boys’ risk behavior. Results suggest that Mexican-origin mothers’ and fathers’ perceptions of work conditions have important implications for multiple domains of adolescents’ adjustment across the transition to high school

Conflict Resolution in Mexican-Origin Couples: Culture, Gender, and Marital Quality

This study examined associations between Mexican-origin spouses’ conflict resolution strategies (i.e., nonconfrontation, solution orientation, and control) and (a) gender-typed qualities and attitudes, (b) cultural orientations, and (c) marital quality in a sample of 227 couples. Results of multilevel modeling revealed that Mexican cultural orientations were positively associated with solution orientation, and Anglo cultural orientations were negatively associated with nonconfrontation. Expressive personal qualities were negatively associated with control, whereas instrumental qualities were positively related to control. Links between conflict resolution and marital quality revealed that control and nonconfrontation were associated with spouses’ ratings of marital negativity. In some cases, different patterns emerged for husbands and wives. Discussion highlights the role of culture and gender dynamics in marital relationships

Exploring Mothers’ and Fathers’ Relationships with Sons Versus Daughters: Links to Adolescent Adjustment in Mexican Immigrant Families

Drawing on ecological and gender socialization perspectives, this study examined mothers’ and fathers’ relationships with young adolescents, exploring differences between mothers and fathers, for sons versus daughters, and as a function of parents’ division of paid labor. Mexican immigrant families (N = 162) participated in home interviews and seven nightly phone calls. Findings revealed that mothers reported higher levels of acceptance toward adolescents and greater knowledge of adolescents’ daily activities than did fathers, and mothers spent more time with daughters than with sons. Linkages between parent-adolescent relationship qualities and youth adjustment were moderated by adolescent gender and parents’ division of paid labor. Findings revealed, for example, stronger associations between parent–adolescent relationship qualities and youth adjustment for girls than for boys

Relations of Parenting Quality, Interparental Conflict, and Overnights with Mental Health Problems of Children in Divorcing Families with High Legal Conflict

The current study examined the associations between child mental health problems and the quality of maternal and paternal parenting, and how these associations were moderated by three contextual factors, quality of parenting by the other parent, interparental conflict, and the number of overnights parents had with the child. Data for the current study come from a sample of divorcing families who are in high legal conflict over developing or maintaining a parenting plan following divorce. Analyses revealed that the associations between child mental health problems and positive maternal and paternal parenting were moderated by the quality of parenting provided by the other parent and by the number of overnights children spent with parents, but not by the level of interparental conflict. When both parenting by the other parent and number of overnights were considered in the same model, only number of overnights moderated the relations between parenting and child behavior problems. The results support the proposition that the well-being of children in high conflict divorcing families is better when they spend adequate time with at least one parent who provides high quality parenting

Mass spectrometry-based proteomic exploration of the human immune system : focus on the inflammasome, global protein secretion, and T cells

Introduction: The immune system is our defense system against microbial infections and tissue injury, and understanding how it works in detail is essential for developing drugs for different diseases. Mass spectrometry-based proteomics can provide in-depth information on the molecular mechanisms involved in immune responses.Areas covered: Summarized are the key immunology findings obtained with MS-based proteomics in the past five years, with a focus on inflammasome activation, global protein secretion, mucosal immunology, immunopeptidome and T cells. Special focus is on extracellular vesicle-mediated protein secretion and its role in immune responses.Expert commentary: Proteomics is an essential part of modern omics-scale immunology research. To date, MS-based proteomics has been used in immunology to study protein expression levels, their subcellular localization, secretion, post-translational modifications, and interactions in immune cells upon activation by different stimuli. These studies have made major contributions to understanding the molecular mechanisms involved in innate and adaptive immune responses. New developments in proteomics offer constantly novel possibilities for exploring the immune system. Examples of these techniques include mass cytometry and different MS-based imaging approaches which can be widely used in immunology.Peer reviewe

Investigation of Polarization Dependent Thomson Scattering in an Energy Recovering Linear Accelerator on the Example of Mesa

At the Johannes Gutenberg University JGU in Mainz, a new accelerator is currently under construction in order to deliver electron beams of up to 155 MeV to two experiments. The Mainz Energy recovering Superconducting Accelerator MESA will offer two modes of operation, one of which is an energy recovering ER mode. As an ERL, MESA, with it?s high brightness electron beam, is a promising accelerator for supplying a Thomson back scattering based Gamma source. Furthermore, at MESA, the polarization of the electron beam can be set by the injector. The aim of this work is to provide a concept and comprehensive analysis of the merit and practical feasibility of a Thomson backscattering source at MESA under consideration of beam polarization and transversal effects. In this paper, an overview and results of our semi analytical approach to calculate various Thomson back scattering light source scenarios at MESA will be given. Furthermore we will discuss the benefits of using polarized electrons in combination with a polarized laser bea

Mexican-Origin Parents’ Latent Occupational Profiles: Associations with Parent-Youth Relationships and Youth Aspirations

This study utilized an ecological, person-centered approach to identify subgroups of families who had similar profiles across multiple dimensions of Mexican-origin mothers’ and fathers’ occupational characteristics (i.e., self-direction, hazardous conditions, physical activity) and to relate these subgroups to families’ sociocultural characteristics and youth adjustment. The study included 160 dual-earner Mexican-origin families from the urban Southwest. Mothers’ and fathers’ objective work characteristics and families’ sociocultural characteristics were assessed when youth were in early to middle adolescence; adjustment was assessed during late adolescence and early adulthood for two offspring in each family. A latent profile analysis identified 3 profiles that evidenced distinct patterns of occupational characteristics: a differentiated high physical activity profile characterized by high levels of physical activity and low levels of self-direction; an incongruent profile characterized by large differences between parents on self-direction, hazards, and physical activity; and a congruent highly self-directed profile characterized by congruence across parents on occupational characteristics. These profiles were linked to sociocultural characteristics (i.e., family income, educational attainment, and acculturation) and to relational adjustment (i.e., mother- and father-youth conflict, father warmth) and educational aspirations. Results are discussed with respect to implications of parents’ work for youth’s future family relationships and attainment

Family Influences on Mexican American Adolescents’ Romantic Relationships: Moderation by Gender and Culture

This study examined prospective associations between the family context and adolescents’ romantic relationships as moderated by adolescents’ gender and culture among Mexican American families (N = 189). Adolescents at Time 1 (early adolescence) were on average 12.29 years of age (SD = .50) and 54% female. Mothers and fathers reported on family structure and dynamics during early adolescence, and youth reported on their romantic relationship involvement and quality during middle and late adolescence. Results from path analyses indicated that family structure and dynamics (supportive parenting, consistent discipline, parent-adolescent, and interparental conflict) were associated with adolescents’ romantic involvement and quality, with differences by adolescents’ gender and culture. Findings highlight Mexican American family contexts that contribute uniquely to adolescents’ romantic relationships
