Collecting Multi-Actor Family Network Data

Abstract Although ‘the family’ is arguably the most fundamental of all social networks, surprisingly little data are available that enable researchers to study the full web of relationships between family members. Mapping family relationships from multiple – preferably ‘all’ – family members’ perspectives enables understanding relational dependencies, such as how parental divorce reverberates through the network. This article introduces a multi-actor family network survey method aimed at collecting ‘complete’ family network data. It discusses the design and implementation of the Lifelines Family Ties project. In this data collection project, a total of 160 children, parents, grandparents, aunts, uncles, and stepfamily members reported on their current and past well-being and their family relationships (contact, support, affection) with 524 family members, resulting in a dataset covering nearly 900 relationships. The article concludes by providing a preview of possible analysis techniques for future users of the Lifelines Family Ties dataset or other future multi-actor family network data.

Effect of Rural-to-Urban Migration on Family Dynamics in Mexico

Purpose: The aim of the study was to analyze the effect of rural-to-urban migration on family dynamics in Mexico. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Rural - urban migration in Mexico has significantly impacted family dynamics, leading to changes in family structure, economic conditions, and social relationships. Migrants often shift from extended family networks to more nuclear family setups, which can alter traditional family roles and support systems. While migration typically improves economic opportunities and educational access, it also introduces challenges such as emotional stress from separation, difficulties in maintaining family ties, and adapting to urban cultural norms. Unique Contribution to Theory, Practice and Policy: Family systems theory, ecological systems theory & social exchange theory may be used to anchor future studies on analyze the effect of rural-to-urban migration on family dynamics in Mexico. Practitioners should develop and implement targeted support programs that address the specific needs of migrant families, such as counseling services, role-specific training, and digital communication tools. Policymakers should create inclusive urban policies that address the challenges faced by migrant families, such as housing affordability, access to education, and social services.

The impact of social capital on the intention of Moroccan university students to engage in social entrepreneurship

PurposeThis research seeks to analyse the process by which undergraduate students make decisions on social entrepreneurship intention (SEI) using the theory of planned behaviour (TPB) model, as well as to comprehend the influence of social capital (SC) on their SEI.Design/methodology/approachThe sample was obtained from the Faculty of Legal, Economic and Social Sciences of Agdal in Rabat, consisting of third-year students enrolled in a bachelor’s or master’s degree programme. The study involved a total of 300 pupils. The authors used the multivariate analytic method known as partial least squares (PLS) to investigate the correlation between different components of our theoretical framework.FindingsSC has demonstrated indirect influences on the development of intentions in the field of social entrepreneurship (SE). The perceived knowledge of the support network has a substantial impact on behavioural control and subjective norms, but it does not influence attitudes. In contrast, the perceived support from the friends and family network has a substantial impact on all three components of the model.Research limitations/implicationsDespite the study’s extensive coverage of several ideas and their consequences in both the theoretical and practical realms, it is important to acknowledge its inherent limitations. The cross-sectional design and use of a student sample may be perceived as restricting considerations.Originality/valueThis research provides valuable insights that support the investments in education, resources and human endeavours made by governmental entities, universities and the private sector. It also supports the initiatives undertaken by management and business schools, as well as trade associations. When individuals establish an intention to engage in SE, whether they act on it immediately or later on or whether they never act on it at all, there is a good signal that mentorship programmes and training in SE have an influence on the process of transitioning towards taking action.

Comprehensive characterization of protease inhibiting gene family, cis-regulatory elements, and protein interaction network in linseed and their expression upon bud fly infestation

Linseed, also known as flax is an important oilseed crop with many potential uses in paint, textile, food and pharmaceutical industries. Susceptibility to bud fly (Dasyneura lini Barnes) infestation is a serious biotic concern leading to severe yield penalty in linseed. Protease inhibitors (PIs) are potential candidates that activate during the insect-pest attack and modulate the resistance. In the present study, we explored the PI candidates in the linseed genome and a total of 100 LuPI genes were identified and grouped into five distinct subgroups. The analysis of cis-acting elements revealed that almost all LuPI promoters contain several regulatory elementary related to growth and development, hormonal regulation and stress responses. Across the subfamilies of PIs, the specific domains are consistently found conserved in all protein sequences. The tissue-specific in-silico expression pattern via RNA-seq revealed that all the genes were regulated during different stress. The expression through qRT-PCR of 15 genes revealed the significant up-regulation of LuPI-24, LuPI-40, LuPI-49, LuPI-53, and LuPI-63 upon bud fly infestation in resistant genotype EC0099001 and resistant check variety Neela. This study establishes a foundation resource for comprehending the structural, functional, and evolutionary dimensions of protease inhibitors in linseed.

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.

How the size and structure of egocentric networks change during a life transition

While social networks are typically relatively stable in size over time, major changes in life circumstances can result in opportunities to acquire new friends. How young adults manage their relationships with their wider network of friends and family during such transitions is, however, not well understood. Using a prospective longitudinal design, we investigate changes in the size and composition of complete egocentric networks of two cohorts of young adults moving away from home to college. We show that, although networks grow rapidly due to an influx of new friends made at college, the social overload that would result is partially mitigated through the progressive loss of pre-transition friendships (but not family relationships). In addition, most of the new relationships are placed in the outermost, emotionally less close network layers that are less costly to maintain. In contrast, the more intimate inner layers of the network remain stable in size, with efforts being made to conserve these relationships. The overriding importance of face-to-face interaction in creating and maintaining ties (compared to digital media) results in the emotional quality of a tie being traded off against the constraints imposed by physical distance. The most reliable predictor of the proportion of original members with whom relationships were maintained post-transition was pre-transition network size, with weaker effects due to geographical proximity and personal popularity in the new social context. These findings have implications for managing transitions to a new environment at any life stage.

What exacerbates and what eases Chinese rural residents’ depression during the COVID-19?

During the COVID-19 pandemic, there has been a growing prevalence of mental disorders, particularly in China, where anti-epidemic measures have been more stringent compared to other countries. This has resulted in a heightened psychological burden on individuals. However, the actual psychological impacts of COVID-19 on Chinese residents have not been clearly established. In this study, we aimed to investigate the effects of various factors, including personal and household characteristics, social networks, and epidemic-related variables (such as rural residents' knowledge of COVID-19 virus transmission and prevention), on rural residents' depression. Using a two-year balanced panel dataset encompassing 152 villages and 676 samples in both 2019 and 2020, we employed the Ordinary Least Squares (OLS) model to estimate the influence of these factors and compare their coefficients to examine the changes in rural residents' depression between the pre-epidemic and during-epidemic periods. Our study highlights significant factors contributing to rural residents' depression during the COVID-19 pandemic, including isolation (2.063, p < 0.01) and concern about COVID-19 infection (0.128, p < 0.05). Conversely, factors such as health status (−0.714, p < 0.01) and the number of friends (−0.017, p < 0.01) were found to significantly alleviate depression among rural residents. Moreover, we identify key moderators that mitigate the negative impact of infection concerns on mental health. Specifically, the health status of rural residents (−0.166, p < 0.01), the size of their family network (−0.036, p < 0.05), and their knowledge of COVID-19 transmission and prevention (−0.184, p < 0.05) significantly moderated the relationship between infection concerns and depression. These findings contribute to a better understanding of the psychological implications of the pandemic and provide valuable insights for the development of targeted interventions to address mental health challenges in rural populations.

Socio-structural determinants of physical activity behavior in children and adolescents: The importance of social support

The purpose of this study is to analyze the influence of socio-structural determinants of physical activity (PA) behavior in children and adolescents. We expected that socioeconomic status, social support, and physical environment influence PA directly while socioeconomic status also has an indirect influence via social support and physical environment. Cross-sectional data from the German Motorik-Modul study (MoMo) were used (Wave 2, 2014–2017). The sample consisted of N = 2134 children and adolescents aged 6–17 years. Socioeconomic status, social support, and physical environment were measured by questionnaires. To measure PA, children and adolescents were instructed to wear accelerometers for seven consecutive days. Moderate-to-vigorous activity periods were considered. Path analyses were used to analyze the direct and indirect effects. We calculated two models, one for children (6–10 years) and one for adolescents (11–17 years). Among children (model 1), only social support had a direct effect on PA behavior. In addition, social support influenced the perceived physical environment. Socioeconomic status had an indirect effect on PA via social support. For adolescents (model 2), all assumed relations were significant and in line with the directions expected. Social support had the strongest direct influence on PA behavior. Socioeconomic status had a direct and indirect effect on PA via the physical environment and social support. The study results emphasize the relevance of close, social networks of families and friends as well as social capital, as a source of social support, for PA levels among young age groups.

Uncovering Names and Connections: The “Polish Jew” Periodical as a Second-Tier Record for Holocaust Remembrance and Network Analysis in Jewish Genealogy

This paper explores the Polish Jew journal as a pivotal second-tier record for advancing Holocaust studies and Jewish genealogy. Traditionally underutilized in academic research, this periodical provides a unique repository of names and narratives of Holocaust victims, filling crucial gaps in primary record collections. The investigation centers on the journal’s potential not only to contribute names to existing databases of Holocaust victims—many of whom are still unrecorded—but also to enhance genealogical methods through the integration of network analysis. By examining Polish Jew, this study illustrates how second-tier records can extend beyond mere supplements to primary data, acting instead as vital tools for reconstructing complex social and familial networks disrupted by the Holocaust. The paper proposes a methodological framework combining traditional genealogical research with modern network analysis techniques to deepen our understanding of Jewish community dynamics during and after World War II. This approach not only aids in identifying individual victims and survivors but also in visualizing the broader interactions within Jewish diaspora communities. This research underscores the significance of Polish Jew in the broader context of Holocaust remembrance. It offers a novel pathway for the future of Jewish genealogical research, advocating for the strategic use of second-tier records in scholarly investigations.

Are children and pension substitutes? Evidence from the new rural pension scheme in China

ABSTRACT The study examines whether children, widely recognized as an important source of old-age security in many societies, reduce people’s demand for a social pension programme in rural China – the New Rural Pension Scheme (NRPS). OLS results suggest that having one more child will lower the NRPS participation rate by 3.0 percentage points and the effect of an additional son is larger than the effect of an additional daughter. However, using fines on unauthorized births under the One Child Policy in China as the instrument of children quantity, I find that the number of children has no causal effect on NRPS participation. Heterogeneity analysis shows that, when all children are adults, the number of children will increase the annual NRPS contribution. These findings suggest that old-age support based on family networks does not necessarily impede the development of formal pension programmes.

Profiling protein-protein interactions to predict the efficacy of B-cell-lymphoma-2-homology-3 mimetics for acute myeloid leukaemia.

B-cell-lymphoma-2 (BCL2) homology-3 (BH3) mimetics are inhibitors of protein-protein interactions (PPIs) that saturate anti-apoptotic proteins in the BCL2 family to induce apoptosis in cancer cells. Despite the success of the BH3-mimetic ABT-199 for the treatment of haematological malignancies, only a fraction of patients respond to the drug and most patients eventually develop resistance to it. Here we show that the efficacy of ABT-199 can be predicted by profiling the rewired status of the PPI network of the BCL2 family via single-molecule pull-down and co-immunoprecipitation to quantify more than 20 types of PPI from a total of only 1.2 × 106 cells per sample. By comparing the obtained multidimensional data with BH3-mimetic efficacies determined ex vivo, we constructed a model for predicting the efficacy of ABT-199 that designates two complexes of the BCL2 protein family as the primary mediators of drug effectiveness and resistance, and applied it to prospectively assist therapeutic decision-making for patients with acute myeloid leukaemia. The characterization of PPI complexes in clinical specimens opens up opportunities for individualized protein-complex-targeting therapies.

Belonging, care, and support: findings from Ottawa’s healthy end of life project

ABSTRACT With a rapidly aging population, Canada has a growing need for public health palliative care services. End of life care, including palliative care, is holistic in nature, paying attention to the physical, psychological, social-cultural, and spiritual needs of the person who is dying and their networks of friends, family, and caregivers. Public health approaches to palliative care work to strengthen community capacities to provide care in tandem with medical and social services. This study reports on the findings of the Healthy End of Life Project (HELP Ottawa), a 4.5-year community-based research project, to demonstrate the importance of including faith communities in public health palliative care initiatives. Focusing on Christian faith communities, this article explores how faith communities can best build the capacity to offer, ask for, and accept support for members who are living with advanced illness, caregiving, or grieving.

'In our culture, we come when you die': Qualitative descriptive analysis of end-of-life perspectives in a reservation-based community.

To explore (1) perspectives and attitudes of Native Americans regarding transitions from serious illness to death, and (2) awareness about hospice and palliative care service models in a Great Plains reservation-based community. Qualitative descriptive study. Community members and clinicians were invited to participate in a semi-structured focus group or interview by Tribal Advisory Board members. Analysis involved three phases: (1) qualitative descriptive analysis of preliminary themes using the Addressing Palliative Care Disparities conceptual model; (2) a cultural review of the data; and (3) reflexive thematic analysis to synthesize findings. Twenty-six participants engaged in two focus groups (n = 5-6 participants in each) and interviews (n = 15). Four themes were derived from their stories: (1) family connectedness is always priority; (2) end-of-life support is a community-wide effort; (3) everyone must grieve in their own way to heal; and (4) support needs from outside the community. Findings highlight cultural considerations spanning the life course. Clinicians, researchers and traditional wisdom keepers and practitioners, particularly those working in rural and/or reservation-based settings, must provide culturally safe care. This must include acknowledging and prioritizing the needs and preferences of Native American patients and the impact on their families and communities. Leveraging community assets, such as family and social networks, is key for supporting Native American patients with serious illnesses. Additionally, facilitating greater family and caregiver involvement along a patient's care trajectory may be a pathway for easing health care workers' caseloads in reservation-based areas, where resources are limited. The Consolidated Criteria for Reporting Qualitative Research (COREQ) guideline was used. The study was ideated based on community insight. Tribal Advisory Board members oversaw all aspects including recruitment, data acquisition, interpretation of findings and tribal data dissemination.

Who is Mobilized to Vote by Short Text Messages? Evidence from a Nationwide Field Experiment with Young Voters

AbstractUsing a large randomized controlled trial and rich individual-level data on eligible voters and their household members, we evaluate how get-out-the-vote (GOTV) appeals affect inequalities in voting, transmit from treated to untreated individuals within households, and how the transmission of voting decisions through family networks influences inequalities in voting. We find that receiving a text message reminder before the Finnish county elections in 2022 mobilized mainly low-propensity voters. As a result, the GOTV intervention reduced existing social inequalities in voting within the target group of young voters. We remarkably find that over 100% of the direct treatment effect spilled over to untreated household members. These spillovers reduced inequality in political participation among the older voters who were not part of the target group. Overall, our results exemplify how randomized controlled trials with a limited focus on the analysis of individuals in the treatment and control groups alone may lead to misestimating the compositional effects of get-out-the-vote interventions.

NanoRanger enables rapid single-base-pair resolution of genomic disorders

Delineating base-resolution breakpoints of complex rearrangements is crucial for an accurate clinical understanding of pathogenic variants and for carrier screening within family networks or the broader population. However, despite advances in genetic testing using short-read sequencing (SRS), this task remains costly and challenging. This study addresses the challenges of resolving missing disease-causing breakpoints in complex genomic disorders with suspected homozygous rearrangements by employing multiple long-read sequencing (LRS) strategies, including a novel and efficient strategy named nanopore-based rapid acquisition of neighboring genomic regions (NanoRanger). NanoRanger does not require large amounts of ultrahigh-molecular-weight DNA and stands out for its ease of use and rapid acquisition of large genomic regions of interest with deep coverage. We describe a cohort of 16 familial cases, each harboring homozygous rearrangements that defied breakpoint determination by SRS and optical genome mapping (OGM). NanoRanger identified the breakpoints with single-base-pair resolution, enabling accurate determination of the carrier status of unaffected family members as well as the founder nature of these genomic lesions and their frequency in the local population. The resolved breakpoints revealed that repetitive DNA, gene regulatory elements, and transcription activity contribute to genome instability in these novel recessive rearrangements. Our data suggest that NanoRanger greatly improves the success rate of resolving base-resolution breakpoints of complex genomic disorders and expands access to LRS for the benefit of patients with Mendelian disorders.

Social network of families involved in child neglect: building a multidimensional perspective.

Neglect is one of the most frequently reported forms of violence against children and adolescents, although it has rarely been explored in national studies. In this light, the present study aimed to analyze the personal social network of families involved in negligence against children and adolescents. This work takes a qualitative approach, anchored in the Paradigm of Complexity, conducted with twenty families involved in negligence against children and adolescents in a municipality in the countryside of the state of São Paulo, Brazil. Data collection took place through minimal maps of the personal social network and semi-structured interviews in January 2021. The networks were limited, with little to no interaction among the different services and sectors, and were predominantly homogeneous. Because they have many weakened ties, they are relatively unsupportive, pointing out difficulties in access to work, education, and health. Due to the characteristics of the network, the complexity of the phenomenon of neglect was identified, in which elements condition and perpetuate experiences of absence and fragility. Interprofessional and intersectoral views and actions are requested and recommended.

Coping and end-of-life decision-making in ALS: A qualitative interview study.

How do people with amyotrophic lateral sclerosis (PALS) deal with their diagnosis and engage in end-of-life decision-making? What informational or supportive needs do they have for counselling about life-sustaining treatment and end-of-life care? Which correlating conditions and influences relate to these needs and how do they connect to the wish to die or wish to live? We conducted a qualitative interview study with 13 people with ALS in Germany from March 2019 to April 2021. Data collection and analysis followed a grounded theory-based approach and revealed close relationships between coping, informational needs and the preparedness for decision-making. We identified the coping strategies 'avoid thinking about end-of-life' and its counterpart, 'planning ahead to be well-prepared,' and differentiated the latter into the patterns 'withdrawing from life and taking precautions against life-prolongation' and 'searching for a new meaning in life and preparing for life-sustaining treatment'. The approaches are based on individual perceptions, attitudes and motives and can be positively/negatively reinforced by healthcare professionals (HCP), family and other interpersonal networks, but also by disease progression and in reaction to health care services. Type and degree of needs concerning information and counselling differed according to coping strategies. These strategies may vary over time, resulting in different support needs. Our findings signify that deep insight is needed into PALS' coping processes to understand their decision-making about life-sustaining treatment. Healthcare professionals should be sensitive to illness experiences beyond medical aspects and foster coping as a biographical process to better support people with ALS.

Red River Jig Family Network

This article describes the first year of a transdisciplinary inquiry into the cultural and historic impact of the “Red River Jig,” a piece of music, dance, and story central to the Michif/Métis peoples. We outline the project’s provenance, review its objectives, and offers four approaches that have emerged in the first year. These include building on visiting as a Métis-specific methodology by applying “visiting way” methodology to the study of music/dance/story while also considering music/dance/story as Métis methodology; moving beyond the disciplinary boundaries; and supporting the flourishment of music/dance/story in Métis communities by building a knowledge-sharing community beyond academic spaces.
