How do school experiences in adolescence affect educational investment in adulthood? The case of parental investment in private tutoring in Germany

AbstractThis article examines the role of parents’ school experiences in adolescence on their educational investment strategies for their own children in middle adulthood. We focus our analysis on the parents’ decision to organize private tutoring (also called shadow education) for their children. Previous international research largely agrees that families with a high socioeconomic status (SES) are more likely to invest in tutoring to achieve competitive advantages in the educational race for higher credentials and maintain a high social status. In Germany, however, recent studies suggest that tutoring in Germany primarily serves underperforming children from les educated families to acquire relatively higher school degrees by compensating the higher demands of academic school tracks. We propose a theoretical decision model based on rational choice and life course theory incorporating psychological factors related to school performance of the parents (such as performance anxiety and ability self-concept) and operationalize four components that are intended to explain the (un)equal use of tutoring: (1) children’s school background, (2) parents’ cost and (3) benefit considerations, as well as (4) parents’ school biography. In addition, we hypothesize on the intergenerational transmission of performance-related factors from parents to their children and how this affects SE investment. We test our hypotheses quantitatively through logit regressions and a structural equation model using unique longitudinal data for 558 families (parents and their children) from the German “LifE” study (1979–2012). Our study produced two key findings: On the one hand, the parents’ previous school performance plays a direct role in the extent to which they themselves are able to provide their children with the necessary support in the event of poor performance. On the other hand, the performance-related experiences of the parents during school are to a certain extent transmitted to their children and thus influence their grades, ability self-concept and performance anxiety. These factors, in turn, are decisive for the decision to organize SE. Our findings indicate that instead of reducing the decision-making process for SE to absolute dimensions of student performance and parents’ SES and related cost-benefit calculations, dynamic factors behind this family decision related to intergenerational transmission and individual characteristics should be considered.

INTERGENERATIONAL TRANSMISSION OF MATERNAL EMPLOYMENT AND DAUGHTERS' CAREER PATHS: EVIDENCE FROM THE 2021 FAMILY STRUCTURE SURVEY

The study investigates the intergenerational transmission of maternal employment to daughters’ employment outcomes using data from the 2021 Family Structure Survey. The results of estimations based on a linear probability model (LPM) and a probit model indicate a positive link between maternal employment and daughters’ employment. Furthermore, multinomial logistic regression results demonstrate that mothers working as salaried workers increases the probability of daughters to work as salaried workers. Similarly, mothers who have been employed as unpaid family workers transmit this employment status to their daughters. This pattern is consistent for mothers who have held positions as day laborers, employers, or have been self-employed, as they also influence their daughters’ employment in similar roles. The estimation findings also highlight the significant impact of higher education on the likelihood of daughters becoming salaried workers, indicating that higher levels of education substantially contribute to this outcome. The study provides valuable evidence into the intergenerational influence of maternal employment on daughters’ career paths.

Young Adult’s Outlook on Marriage: The Influence of Parental Divorce, Family of Origin Functioning and Attachment Style

ABSTRACT To elucidate reasons for the variability in attitudes toward marriage held by adult children of divorce, the current, mixed-methods study examined the influence of parental divorce and remarriage(s), family of origin functioning and attachment style variables on young adults’ attitudes toward marriage. Participants who experienced their parents’ divorce, perceived high levels of conflict in their family of origin, were single and presented with discomfort in close relationships were more likely to express negativity in their outlook on marriage. Participants who denied religiosity and perceived their parents as encouraging independence while growing up were more likely to express an ambivalent attitude toward marriage. Lastly, men and those who had experienced their parents remarriage(s) were more likely to express positivity in their outlook on marriage. Although other factors were influential, parental divorce may promote negativity in young adults’ attitudes toward marriage, which possibly contributes to the “intergenerational transmission of divorce.”

Cadmium Exposure in Male Rats Results in Ovarian Granulosa Cell Apoptosis in Female Offspring and Paternal Genetic Effects.

The aim of this study was to investigate whether the damage to male offspring induced by cadmium (Cd) exposure during embryonic period leads to the apoptosis of ovarian granulosa cells (OGCs) in the next generation of female offspring, and whether this apoptosis in the offspring was due to paternal genetic effects. Pregnant Sprague-Dawley (SD) rats were exposed to CdCl2 (0, 0.5, 2.0, or 8.0 mg/kg) by gavage daily for 20 days to produce the filial 1 (F1) generation. F1 males were mated with newly purchased females to produce the F2 generation, and the F3 generation was generated in the same way. No apoptotic bodies were observed in the OGCs of either the F2 or F3 generation as shown by electron microscopy, and a reduced OGC apoptosis rate (detected by flow cytometry) was observed in F2 OGCs from the Cd-exposed group. Moreover, the mRNA (qRT-PCR) levels of Bax and Bcl-2 and the protein (western blotting) level of pro-caspase-8 increased in the F2 generation (p < 0.05). The expression of apoptosis-related miRNAs (qRT-PCR) and methylation of apoptosis-related genes (determined via bisulfite-sequencing PCR) in OGCs were further determined. Compared with those of the controls, the expression patterns of microRNAs (miRNAs) in the F2 offspring were different in the Cd-exposed group. The miR-92a-2-5p expression levels were decreased in both the F2 and F3 generations (p < 0.05), while the average methylation level of apoptosis-related genes did not change significantly (except for individual loci). In summary, this study showed that the paternal genetic intergenerational effect of male Cd exposure during embryonic period induced apoptosis of OGCs in the offspring was weakened, and the transgenerational effect disappeared; nevertheless, intergenerational and transgenerational changes in apoptosis-related genes, epigenetic modifications, DNA methylation, and miRNAs were observed, and may be important for understanding the homeostatic mechanisms of the body to alleviate the intergenerational transmission of Cd-induced damage.

Planning and teaching heritage languages in the translocal and digital space

ABSTRACT This Special Issue came about as the result of the COVID-19 pandemic, which brought unprecedented shifts in the conditions and opportunities for language education. In the context of heritage languages, there were significant challenges for learners, parents, and teachers, but there were also new opportunities for rethinking the ways in which languages were taught and passed on to the next generation. In this Special Issue, we take an ecological perspective on language policy and planning (henceforward LPP) and focus on micro- and meso-level LPP related to language learning and the intergenerational transmission of heritage languages. While the approach taken in this volume aligns with the notion that macro, meso and micro perspectives, goals and activities are not independent of each other but form a complex ecology (Baldauf, 2006), our focus here is not on formal policy making and implementation, but on the practices surrounding language learning, teaching and use, as forms of LPP (Liddicoat, 2020).

Exploring perceptions of genetic risk and the transmission of substance use disorders

BackgroundSubstance use disorders (SUDs) have been consistently shown to exhibit moderate intergenerational continuity (1–3). While much research has examined genetic and social influences on addiction, less attention has been paid to clients’ and lay persons’ perceptions of genetic influences on the heritability of SUD (4) and implications for treatment.MethodsFor this qualitative study, twenty-six structured Working Model of the Child Interviews (WMCI) were conducted with mothers receiving inpatient SUD treatment. These interviews were thematically analyzed for themes related to maternal perceptions around intergenerational transmission of substance use behaviours.ResultsFindings show that over half of the mothers in this sample were preoccupied with their children’s risk factors for addictions. Among this group, 29% spontaneously expressed concerns about their children’s genetic risk for addiction, 54% shared worries about their children’s propensity for addiction without mentioning the word gene or genetic. Additionally, 37% had challenges in even discussing their children’s future when prompted. These concerns mapped onto internal working models of attachment in unexpected ways, with parents who were coded with balanced working models being more likely to discuss intergenerational risk factors and parents with disengaged working models displaying difficulties in discussing their child’s future.ConclusionThis research suggests that the dominant discourse around the brain-disease model of addictions, in its effort to reduce stigma and self-blame, may have unintended downstream consequences for parents’ mental models about their children’s risks for future addiction. Parents receiving SUD treatment, and the staff who deliver it, may benefit from psychoeducation about the intergenerational transmission of SUD as part of treatment.

Is the impact of the South African child support grant on childhood stunting robust? An instrumental variable evaluation

The Child Support Grant (CSG) is part of the South African Social Assistance Programme, which costs the country approximately 1.3% of GDP annually. Given the scale of this programme, it is important to assess whether it has had an impact on the long-term health outcomes of children. Extant literature on the impact of CSG on a child’s long run nutritional status as measured by the height-for-age relies on the optimistic assumption that estimation controls for all relevant variables (i.e. the ignorability assumption). Further existing analysis are based on older datasets (i.e. older waves of the National Income Dynamic Study (NIDS)). We examine the robustness of the results to bias due to unobserved variables, using more recent data (the 2014/2015 and 2017 NIDS). Using the possession of the necessary government-issued documentation to access the grant as an instrumental variable (IV) we find that existing results are robust to the IV framework. Further, acknowledging the limitation of the instrumental variable, we show that the result is robust to violation of various assumptions underlying the IV approach. We argue that while the CSG remains a crucial contributor to early childhood development in South Africa, there is a need to critically examine its impact on nutritional status given the importance of this variable for intergenerational transmission of poverty.

Shades of complicity: archives of the ‘implicated subject’

AbstractKnowledge of the Arandora Star is no longer limited to members of the UK's historic Italian community but is shared by a much larger constituency thanks to the greater accessibility of historical documents relating to the sinking of the ship, and to the substantial volume of new creative work inspired by it. This article examines this expansion of historical memory by following two discrete but entangled strands. The first follows the construction of the Arandora Star archive, starting from the author's chance personal encounter with a photograph. The second involves a close reading of Francine Stock's A Foreign Country (1999) and Caterina Soffici's Nessuno può fermarmi (2017), two novels that explore how people outside the historic Italian community recognise their implication in the sinking and its aftermath. Both foreground the intergenerational and transnational transmission of difficult memory and the ways in which the Arandora Star functions as an unstable point of historical knowledge and ethical judgement.

A Multigenerational Model of Environmental Risk for Black, Indigenous, and People of Color (BIPOC) Children and Families.

In recent years, public discourse has increasingly brought institutional and structural racism to the foreground of discussion on the well-being of BIPOC (Black, Indigenous, and People of Color) communities. Environmental toxicity in combination with the social triggers of institutional and structural racism are among the factors that shape the short- and long-term health of BIPOC Americans across multiple lifespans. We outline a Generation Model for examining the mechanisms through which institutional and structural racism promotes the intergenerational transmission of environmental health risk and family and interpersonal relationships across the life course and across multiple generations. We present the model's theoretical underpinnings and rationale, discuss model limitations and needed sources of data, and implications for research, policy, and intervention. Parents and children are not only biologically linked in terms of transmission of environmental toxicities, but they are also linked socially and intergenerationally. The Generation Model foregrounds family and interpersonal relationships occurring within developmental contexts that are influenced by environmental toxicity as well as institutional and structural racism. In sum, the Generation Model highlights the need for an equity-first interdisciplinary approach to environmental health and redirects the burden of risk reduction away from the individual and onto the institutions and structures that perpetuate the racial disparities in exposure. Doing so requires institutional investment in expanded, multigenerational, and multimethod datasets. https://doi.org/10.1289/EHP13110.

Intergenerational transmission of sucralose and acesulfame-potassium from mothers to their infants via human milk: a pharmacokinetic study

BackgroundLow-calorie sweetener (LCS) consumption is prevalent among lactating mothers, yet infants’ exposure to LCS in human milk is not well-characterized. ObjectivesConduct a pharmacokinetic study of sucralose and acesulfame-potassium (ace-K) in mothers’ milk and plasma over 72 h and in infants’ plasma. MethodsFollowing baseline blood and milk collection, mothers (n = 40) consumed 20 oz of diet cranberry juice containing sucralose and ace-K. Blood samples were collected from the mother 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, and 72 h after beverage ingestion, and milk was expressed at 1, 2, 3, 4, 6, 8, 12, and 24 h postingestion. One blood sample was collected from each infant, the timing of which was determined using pharmacokinetics model-based simulation. Concentration-time profiles of LCS from the mother’s plasma and milk were analyzed using noncompartmental methods. ResultsAce-K rapidly entered human milk with the largest observed concentration of 373.0 (coefficient of variation 69%) ng/mL first detected 4 h following diet beverage ingestion. Sucralose appeared in human milk 1–2 h after diet beverage ingestion with the largest observed concentration of 7.2 (coefficient of variation 63%) ng/mL first detected 7 h postingestion. The mean 24-h milk to plasma ratio of ace-K was 1.75 [standard deviation (SD) 1.37] with a mean relative infant dose of 1.59% (SD 1.72%). Ace-K was detected in all infants’ plasma with an mean concentration of 9.2 (SD% 14.8) ng/mL ∼6 h after maternal beverage ingestion. The mean 24-h milk to plasma ratio of sucralose was 0.15 (SD 0.06) with a mean relative infant dose of 0.04% (SD 0.02%). Sucralose was detected in only 15 infants’ plasma, and the mean concentration was 5.0 (SD% 7.1) ng/mL ∼5 h after diet beverage ingestion. ConclusionsAce-K rapidly transfers from human milk into infants’ circulation whereas sucralose was detected at much lower concentrations and in some but not all infants. Future research should investigate the effects of early-life sucralose and ace-K exposure via human milk on infants’ health.This trial was registered at clinicaltrials.gov as NCT05379270.

Historical Patterns in the Intergenerational Transmission of Lifespan and Longevity: A Research Note on U.S. Cohorts Born Between 1700 and 1900

This research note examines historical trends in lifespan inequality and the intergenerational transmission of lifespan and longevity in the United States over the eighteenth, nineteenth, and twentieth centuries. We contribute to the literature by expanding the estimates of the familial component beyond parent–child associations to include multigenerational and horizontal classes of relatives of different sexes. We also examine how lifespan inequality and the role of the family in lifespan and longevity changed over time. We address the challenge of studying extended family networks in historical times by leveraging recent online crowdsourced genealogical data. Results confirm the presence of a familial component for all classes of relatives considered and highlight a stronger association for horizontal than for vertical relationships. Despite decreasing lifespan inequality, we find no evidence of decreased familial lifespan stratification throughout history. If anything, the results suggest a strengthening of the parent–child association. Finally, the results contribute to the debate on the representativeness and usability of crowdsourced genealogical data by emphasizing the importance of sample selection based on the quality of the information collected.

Psychiatric Diagnoses in Parents and Psychiatric, Behavioral, and Psychosocial Outcomes in Their Offspring: A Swedish Population-Based Register Study.

Associations were examined between six psychiatric diagnoses in parents and a broad range of psychiatric and nonpsychiatric outcomes in their offspring. All individuals born in Sweden between 1970 and 2000 were linked to their biological parents (N=3,286,293) through Swedish national registers. A matched cohort design, with stratified Cox regression and conditional logistic regression analyses, was used examine associations between six psychiatric diagnoses in the parents and 32 outcomes in their offspring. All children, including those exposed and those not exposed to parents with psychiatric diagnoses, were followed from their date of birth to the date of emigration from Sweden, death, or December 31, 2013, when the offspring were 14-44 years old. In terms of absolute risk, most children who had parents with psychiatric diagnoses were not diagnosed in specialist care themselves, and the proportion of offspring having any of the 16 types of psychiatric conditions ranged from 22.17% (of offspring exposed to parental depression) to 25.05% (of offspring exposed to parental drug-related disorder) at the end of follow-up. Nevertheless, in terms of relative risk, exposure to any of the six parental psychiatric diagnoses increased probabilities of the 32 outcomes among the offspring, with hazard ratios that ranged from 1.03 to 8.46 for time-to-event outcomes and odds ratios that ranged from 1.29 to 3.36 for binary outcomes. Some specificities were observed for parental diagnoses of psychosis and substance-related disorders, which more strongly predicted psychotic-like and externalizing-related outcomes, respectively, in the offspring. The intergenerational transmission of parental psychiatric conditions appeared largely transdiagnostic and extended to nonpsychiatric outcomes in offspring. Given the broad spectrum of associations with the outcomes, service providers (e.g., psychiatrists, teachers, and social workers) should consider clients' broader psychiatric family history when predicting prognosis and planning interventions or treatment.

Construction and intergenerational transmission of the perception of volcanic risk in Mexico

Many populations live around active volcanoes with the uncertainty of a possible big eruption, as is the case of the populations near Popocatépetl in Mexico, which began a period of activity in 1994. The risk perception of these populations is complex to manage, due to factors such as territorial rootedness, social identity, cultural factors, as well as diverse positions among generations. A qualitative research was conducted in the municipality of Tetela del Volcán in Mexico, located in a high volcanic risk zone. The main objective of this work was to analyze the social construction of the perception of volcanic risk considering the exchange of knowledge between different generations. An ethnographic and participatory study was carried out from symbolic interactionism, using elements of grounded theory and deductive elements for the analysis of information. The participants were adolescents, adults, and seniors from different social sectors. The results allowed the construction of a theoretical mapping of the processes of intergenerational construction of volcanic risk perception. It was found that different generations coexist, including adults born during the current period of volcanic activity. Also, risk perception is constructed from the integration of three dimensions: 1) culture and environment, 2) socio-cognition and emotions, and 3) responses to volcanic risk. From these findings it is possible to understand the continuities and social transitions of different generations coexisting with the Popocatépetl risk and uncertainty. This work can help decision makers improve public policies, risk management practices, and risk communication strategies and disaster risk reduction.

The Evolution of Domestic Abuse as a Process (DAP) Model: An Initial Statement

A new model of intimate partner violence, the Domestic Abuse Process (DAP) model, is presented to address how domestic abuse emerges, evolves, and escalates in a romantic relationship over time. A review of the relevant literature on intimate partner violence, including studies examining the role of resources, relationship goals and means for achieving these goals, and relationship stressors is conducted. Important theories such as symbolic interactionism, strain, intergenerational transmission of violence, and the process model of family violence are also reviewed and discussed within the context of domestic abuse. A short discussion of how the proposed model could be empirically tested using a survey instrument containing numerous items that are administered to respondent couples is provided. Follow-up interviews with respondent couples would be used to clarify survey responses and to obtain more detailed insights into how abuse entered and intensified in respondent relationships. Both quantitative and qualitative analyses would be performed on the subsequent data to glean important factors and patterns empirically involved in the process. The model provides additional insights into intimate partner violence and abuse that could inform treatment practices and policy.

Effects of Parental Childhood Maltreatment on Children's School Adaptation: An Intergenerational Perspective Based on Envy.

Previous studies have examined the impact of maternal childhood maltreatment (CM) on children's school adaptation (SA), neglecting the role of fathers, and the joint influence of both parents. Based on family systems theory, this study explored the intergenerational impact of parental CM on children's SA and the mediating role of benign envy (BE) and malicious envy (ME). A total of 334 elementary school students' BE, ME, and SA statuses and their parents' CM, BE, and ME statuses were collected to construct the intergenerational transmission models of BE and ME for fathers, mothers, and parents, respectively. The results revealed that maltreated fathers or mothers individually exerted negative impacts on their children's SA, but when parents acted jointly, only fathers' CM intergenerational influence was significant. Mediation effects demonstrated that, individually, maltreated fathers indirectly affected children's SA through children's BE; maltreated mothers impacted children's SA through the "mothers' BE→children's BE" mediating chain; however, when taking combined parental action, only mothers' intergenerational transmission chain was significantly present. Identifying different intergenerational influence mechanisms of maltreated parents on offspring's school adaptation broadens our understanding of the diverse parenting roles of parents. That is, fathers foster their offspring's environmental adaptability through encouraging external exploration, while mothers enhance socialization by nurturing internal emotional development. Formulating strategies to address the emotional issues of maltreated parents, especially mothers, is crucial for mitigating the intergenerational consequences of maltreatment and enhancing the offspring's adaptability.

Parental exposure to acrylamide disrupts sphingolipid metabolism and impairs transgenerational neurodevelopment in zebrafish (Danio rerio) offspring

Acrylamide exposure has become an emerging environmental and food safety issue, and its toxicity poses a potential threat to public health worldwide. However, limited studies have paid attention to the detrimental effects of parental exposure to acrylamide on the neurodevelopment in zebrafish offspring. In this study, the embryos were life-cycle exposed to acrylamide (0.125 and 0.25 mM) for 180 days. Subsequently, these zebrafish (F0) were allowed to mate, and their offspring (F1) were collected to culture in clean water from embryos to adults. We employed developmental and morphological observations, behavioral profiles, metabolomics analyses, and transcriptional level examinations to investigate the transgenerational neurotoxicity with parental exposure to acrylamide. Our results showed that parental exposure to acrylamide harms the birth, development, and behavior characterization of the F1 zebrafish larvae, including poor egg quality, increased mortality rates, abnormal heart rates, slowed swimming activity, and heightened anxiety behavior, and continuously disturbs mental health in F1 adult zebrafish. The transcriptional analysis showed that parental chronic exposure to acrylamide deteriorates the neurodevelopment in F1 larvae. In addition, metabolomics analyses revealed that sphingolipid metabolism disruption may be associated with the observed abnormal development and behavioral response in unexposed F1 offspring. Overall, the present study provides pioneer evidence that acrylamide induces transgenerational neurotoxicity via targeting and disrupting sphingolipid metabolism, which reveals intergenerational transmission of acrylamide exposure and unravels its spatiotemporal toxicological effect on neurodevelopment.

Young people's experiences and use of violence in the home: Examining four types of child maltreatment, their intersections and self-reported use of violence in the home

BackgroundChild maltreatment has received substantial academic attention. However, little remains known about the intersection of different types of child maltreatment and their association with young people's use of violence in the home. ObjectiveTo examine the intersection of child maltreatment types and the intergenerational transmission of violence through young people's use of violence in the home. Participantsand setting: A total of 5021 young people (16–20 years old) completed an online survey, recruited using non-probability sampling via survey panels. MethodsAnalyses were carried out using χ2 tests and a series of binary logistic regressions to examine the association between participant characteristics and unique child maltreatment experiences with different forms of maltreatment and young people's use of violence. ResultsOverall, 29.9% of participants had experienced at least one form of maltreatment and 16.7% reported experiences of multi-type maltreatment. The most common experiences were childhood experiences of domestic violence (CEDV) (27.3%), followed by verbal/emotional abuse (17%), which both increased the likelihood of also experiencing physical abuse (OR = 5.85 and OR = 10.21, respectively). Cisgender females and children living with a disability were more likely to experience all four types of maltreatment. Experiences of verbal/emotional abuse (OR = 4.56), and CEDV (OR = 4.52) increased the risk of young people's use of violence in the home. ConclusionsFindings contribute to a growing body of work recognising CEDV as a distinct form of child maltreatment which intersects with other experiences of abuse, including young people's use of violence in the home.

Intergenerational Storytelling and Positive Psychosocial Development: Stories as Developmental Resources for Marginalized Groups

Academic We articulate an intergenerational model of positive psychosocial development that centers storytelling in an ecological framework and is motivated by an orientation toward social justice. We bring together diverse literature (e.g., racial-ethnic socialization, family storytelling, narrative psychology) to argue that the intergenerational transmission of stories about one’s group is equally important for elders and youth, and especially important for groups who are marginalized, because stories provide a developmental resource for resistance and resilience in the face of injustice. We describe how storytelling activities can support positive psychosocial development in culturally dynamic contexts and illustrate our model with a case study involving LGBTQ+ communities, arguing that intergenerational storytelling is uniquely important for this group given issues of access to stories. We argue that harnessing the power of intergenerational storytelling could provide a culturally safe and sustaining practice for fostering psychosocial development among LGBTQ+ people and other equity-seeking populations. Public Understanding one’s identity as part of a group with shared history and culture that has existed through time is important for positive psychological functioning. This is especially true for marginalized communities for whom identity-relevant knowledge is often erased, silenced, or distorted in mainstream public discourses (e.g., school curricula, news media, television, and film). To compensate for these limitations around access, one channel for the transmission of this knowledge is through oral storytelling between generations of elders and youth. Contemporary psychological science has often assumed that such storytelling occurs within families, but when families cannot or would not share such knowledge, youth suffer. We present a model of intergenerational storytelling that expands our ideas around who counts as “family” and how knowledge can be transmitted through alternative channels, using LGBTQ+ communities as a case example.
