Despite the wide existence of vesicles in living cells as well as their important applications like drug delivery, the underlying mechanism of vesicle fusion/fission remains under debate. Classical models cannot fully explain recent observations in experiments and simulations. Here, we develop a constrained self-consistent field theory that allows tracking the shape evolution and free energy as a function of center-of-mass separation distance. Fusion and fission are described in a unified framework. Both the kinetic pathway and the mechanical response can be simultaneously captured. By taking vesicles formed by polyelectrolytes as a model system, we predict discontinuous transitions between the three morphologies: parent vesicle with a single cavity, hemifission/hemifusion, and two separated child vesicles, as a result of breaking topological isomorphism. With the increase in inter-vesicle repulsion, we observe a great reduction in the cleavage energy, indicating that vesicle fission can be achieved without hemifission, in good agreement with simulation results. The force–extension relationship elucidates typical plasticity for separating two vesicles. The super extensibility in the mechanical response of vesicle is in stark contrast to soft particles with other morphologies, such as cylinder and sphere. Our work elucidates the fundamental physical chemistry based on intrinsic topological features of vesicle fusion/fission, which provides insights into various phenomena observed in experiments and simulations.

This study aimed to describe the experiences of the female teachers who are single parents by focusing on the description of their significant experiences, their coping mechanisms, and the insights that they can share. The researcher employed a qualitative-phenomenological approach as the research design. The participants of the study were the ten teachers for the in-depth interview and ten teachers for the focus group discussions. These teachers are from the Municipality of Alabel, Province of Sarangani. The findings indicated that in the experiences of the teachers, four (4) emergent themes emerged, and these are: patiently taking responsibilities, good in managing time, experiencing financial instability, and becoming optimistic. On the other hand, in terms of the coping mechanism of the teachers, six (6) major themes emerged when the data was analyzed: overwhelming support from significant others, enriching one's spirituality, loving oneself, acceptance of the reality, possessing stronger personality, and focusing on the responsibilities. Lastly, in terms of the insights that the female single parents could share based on their experiences, six (6) major themes emerged: resiliency, feeling the pain until it hurts no more, never forget to pray, face life positively, managing finances well and be an inspiration. These could become the basis in crafting specific programs and projects which would benefit the female teachers who are single parents. [ABSTRACT FROM AUTHOR]

Despite extensive studies on academic achievement, the unique challenges and resilience of students from singleparent households remain underexplored. Through purposive sampling, this phenomenological research explored the lived experiences of nine (9) senior high school students from a well-known performing arts school in Quezon City who grew up in a single-parent household. A researcher-made interview protocol with ten (10) open-ended questions that was validated by renowned experts was administered to gather responses and sufficient, vital information from the participants. With the utilization of Interpretative Phenomenological Analysis, three (3) superordinate themes were generated: (1) challenges encountered which delves to the emotional, supportive and financial encounters of the participants; (2) experiences of growing up in a single parent household which pertains to the new responsibilities alongside with the bullying and social challenges faced by the participants; and, (3) emotional well-being which covers the participants' emotional struggles, negative outlook on personal future and their hopes for future family life.

As the world continues to struggle with the effects of the COVID-19 pandemic, there has been much speculation on the impact of the virus on crime rates, especially domestic violence. Researchers have largely adopted a routine activities explanation for increased levels of domestic violence, where disruptions in patterns of daily life caused by lockdowns increased the opportunity for such events to occur. The purpose of this manuscript was to utilise emerging hot spot analysis to explore spatiotemporal changes in the number of calls for service for domestic disturbance from 1 March 2020 – 31 December 2020 in the City of Tampa, FL USA based on critical time frames for restrictions and recovery. As predicted by opportunity theory, there was a statistically significant decline in the counts of calls over the 10-month period. Additionally, sporadic hot spots were found at some locations during times of heightened restrictions. Locations with sporadic hot spots coincided with census tracts reporting lower education levels; higher levels of poverty, unemployment, single parent households; and more minority residents.

Aim Methods Results Conclusion To assess the prevalence of overweight among Swedish 4 year olds in 2018, 2020 and 2022, taking socioeconomic variables into account.Aggregated regional data on children's body mass index were collected. The socioeconomic Care Need Index (CNI), foreign background, low education, being a single parent, low income and childhood poverty, were assessed. The differences in overweight, including obesity, were tested for Sweden and for regions.Data were available for 303 843 children, representing 87% of children born in 2014, 2016 and 2018. Overweight or obesity were found in 11 177 (11.4%) of children in 2022, decreasing from 2020 (13.3%, p < 0.001) but at the same level as in 2018. Regional low CNI, low level of foreign background, education and income as well as being a single parent were associated with a higher prevalence of overweight or obesity in all cohorts (p < 0.001). In regions with high levels of childhood poverty, overweight or obesity were more prevalent during (p = 0.009) and after the pandemic (p < 0.001).Three national cohorts demonstrate that the increase in overweight during the COVID‐19 pandemic has returned to pre‐pandemic levels, but the inequalities in health associated with socioeconomic vulnerability of the regions remained.

Background: The prevalence and characteristics of household material hardship (HMH) in families of children with advanced cancer and its association with parent distress are unknown and herein described. Methods: Parents of children aged ≥2 years with advanced cancer at five cancer centers completed baseline surveys as part of the PediQUEST Response trial. HMH (housing, energy, and food) was operationalized as binary (≥1 HMH domains), ordinal (zero, one, or two or more HMH domains), and housing based (none, nonhousing [food and/or energy], only housing, or housing + other). Associations between HMH and parent distress measured by the State‐Trait Anxiety Inventory–State and the 10‐item Center for Epidemiologic Studies Depression Scale were estimated via linear models adjusting for confounders. Results: Among 150 parents, 41% reported ≥1 HMH (housing, 28% [only housing, 8%; housing + other, 20%]; energy, 19%; food, 27%). HMH was more prevalent among Hispanic, other non‐White race, Spanish‐speaking, and single parents and those with lower education (associate degree or less) or who were uninsured/Medicaid‐only insured. Parents endorsing HMH reported higher anxiety (mean difference [MD], 9.2 [95% CI, 3.7–14.7]) and depression (MD, 4.1 [95% CI, 1.7–6.5]) scores compared to those without HMH. Distress increased with the number of hardships, particularly housing insecurity. Specifically, parents experiencing housing hardship, alone or combined, reported higher distress (housing only: anxiety: MD, 10.2 [95% CI, 1.8–18.5]; depression: MD, 4.9 [95% CI, 1.3–8.6]; housing + other HMH: anxiety: MD, 12.0 [95% CI, 5.2–18.9]; depression: MD, 4.8 [95% CI, 1.8–7.8]). Conclusions: HMH is highly prevalent in pediatric advanced cancer, especially among historically marginalized families. Future research should investigate whether interventions targeting HMH, particularly housing stabilization efforts, can mitigate parent distress. Plain Language Summary: In our cohort of parents of children with advanced cancer, household material hardship (HMH) was highly prevalent and significantly associated with higher parent distress. Housing hardship was the primary driver of this association.Families of children with advanced cancer may benefit from systematic HMH screening as well as targeted HMH interventions, especially stabilizing housing. The prevalence and characteristics of household material hardship (HMH) in families of children with advanced cancer and its association with parent distress are unknown. This cross‐sectional analysis of 150 parents of children with advanced cancer with baseline data from a multisite parallel randomized controlled trial showed that HMH was highly prevalent and significantly associated with higher parent distress, and that housing hardship was the primary driver of this association.

Single parenting is a difficult thing to do. And when people talk about it, the first thing that comes to mind is a single mother. Masculinity is a term that is linked with men that corners their feelings in an idea that they should be strong. Only a few studies can be found that are focused on the well-being and challenges that a single father faces in childrearing. In this study, the researchers aim to explore about the single fathers' story specifically their lived experiences; (1) explore about single fathers' experiences (2) to know the challenges faced by Single fathers (3) identify the childrearing practices of Single fathers (4) discover the coping mechanisms that single fathers use to cope up with problems. Using a semi- structured interview guide, 3 participants will be interviewed for data gathering and using Thematic Analysis (TA) the study interprets the following: (1) the experiences of the participants shows that most of the Single fathers go through grief and self-neglect. The pressure of providing for their children also causes them to have sacrificial love for their children to the point of overworking for them and forgetting about the well-being of oneself (2) providing the children's need, sharing custody and time management is the most effective way for the participants to take care of their children (3) challenges such as financial, emotional well-being and lack of experience on being a single father are the most common trials that the participants faced (4) the coping mechanisms varies from person to person but the participants of the study cope up with challenges by means of alcoholism, social support and turning to God.

East Asian atmospheric rivers (ARs) exhibit the most pronounced activity in summer with significant impacts on monsoon rainfall. However, their occurrence mechanisms are yet to be revealed in detail. In this study, we unravel the inherently complex nature of East Asian summer ARs by applying a multiscale index that quantifies the relative importance of high-frequency (HF) and low-frequency (LF) moisture transports in AR development. It is found that both HF and LF processes contribute to shaping the summertime ARs in East Asia, contrasting to the wintertime ARs dominated by HF processes. Stratification of ARs with the multiscale index reveals that HF-dominant ARs are driven by baroclinically deepening extratropical cyclones, analogous to the widely accepted definition of canonical ARs. In contrast, LF-dominant ARs result from an enhanced monsoon southwesterly between a quasi-stationary cyclone and an anticyclone with the latter being the anomalous expansion of the western North Pacific subtropical high. Such a pattern is reminiscent of the classical monsoon rainband. While HF-dominant ARs are transient, LF-dominant ARs are quasi-stationary with a higher potential for prolonged local impacts. The intermediate ARs, constituting a majority of East Asian summer ARs, exhibit synoptic conditions that combine HF- and LF-dominant ARs. Therefore, East Asian summer ARs cannot be explained by a single parent system but should be considered as a continuum of extratropical-cyclone-induced and fluctuating monsoon-flow-induced moisture plumes. This finding would serve as a base for the advanced understanding of hydrological impacts, variability, and projected change of East Asian ARs. Significance Statement: Despite the accumulation of studies on summertime atmospheric rivers (ARs) in East Asia, a comprehensive explanation for their occurrence mechanisms remains elusive. This study disentangles their complicated nature through case-level multiscale analyses. In contrast to wintertime ARs, summertime ARs are shaped by both high- and low-frequency moisture transports. The high-frequency moisture transport is associated with migratory extratropical cyclones which are suppressed but still active in summer, while the low-frequency moisture transport arises from the fluctuation of a quasi-stationary monsoon southwesterly along the periphery of the western North Pacific subtropical high. The varying relative contribution of high- and low-frequency components from one AR to another suggests that East Asian summer ARs represent a continuum of extratropical and monsoonal moisture plumes.

Existing research points towards an overall intensification of parenting expectations including newer expectations for fathers' involvement in caregiving. At the same time, the ideal worker norm persists, and employers continue to expect men's full and uninterrupted work commitment. This article explores what these competing expectations attached to work and parenting mean for single fathers. To do so, the article draws on 30 in-depth interviews with a sample of working single fathers with primary caregiving responsibility in the United States and differentiates between those with white- and blue-collar jobs. The study finds that both white- and blue-collar single fathers prioritize caregiving and resist the ideal worker norm and, as a result, experience work–family conflict. Resolving this conflict becomes single fathers' individual responsibility, and the resources to resolve it are primarily available to white-collar men in the form of understanding supervisors and access to workplace flexibility. Blue-collar single fathers need to be more creative and resourceful in reconciling their caregiving and breadwinning roles. Inability to resolve work–family conflict can lead to job penalties such as reduced income and/or a job loss, which are found across different job types. [ABSTRACT FROM AUTHOR]

This study examined the serial mediating effects of negative parenting and children's mastery motivation on the relationship between family socioeconomic status (SES) and internalizing and externalizing problem behaviors in Chinese preschoolers. A sample of 669 Chinese children between 3 and 6 years (Mage = 4.83, SDage = 0.87, 50.4% girls) was recruited from 12 public kindergartens in a coastal city in southeastern China based on a stratified random sampling procedure. Their parents completed the Multidimensional Assessment of Parenting Scale (MAPS), Dimensions of Mastery Questionnaire for Preschool Children (DMQ 18), and Children's Problem Behaviors Scale (CPBS). Research Findings: (1) family SES was significantly related to reduced negative parenting and children's problem behaviors as well as increased children's mastery motivation; (2) family SES affected children's problem behaviors indirectly through the single mediating path of negative parenting and the single mediating path of children's mastery motivation; and (3) negative parenting and children's mastery motivation were identified the serial mediators between family SES and children's problem behaviors. Practice or Policy: This study has demonstrated how family SES would interact with negative parenting practices concerning early childhood development. The findings also indicated that strategies that assist parents in adopting positive parenting practices or facilitate the development of mastery motivation in children might reduce the occurrence of children's problem behaviors.

Background: Data on the association between food insecurity and depression in single parents in low- and middle-income countries (LMICs) are limited, and no study has reported the serial mediation effects of psychosocial factors in this association. This study examines the extent to which anxiety and sleep serially explain the food insecurity and depression link among single parents in Ghana. Methods: Data on 627 single parents were obtained through a multi-stage stratified sampling technique. Food insecurity was assessed using the Food and Agriculture Organization Food Insecurity Experience Scale (FIES), and depression was assessed using the Center for Epidemiological Studies Depression Scale (CES-D-10). Multivariable OLS models and bootstrapping serial mediation analyses were performed to evaluate the hypothesized associations. Results: The mean age (SD) was 45.0 (14.7) years; 67.3% females. After full adjustment, food insecurity was significantly associated with increases in anxiety symptoms (β = 0.61, 95%CI = 0.476 − 0.737), sleep problems (β = 0.04, 95%CI = 0.02 − 0.07), and depression (β = 0.24, 95%CI = 0.12 − 0.36). Food insecurity indirectly related to depression via anxiety (β = 0.35, 95%CI = 0.26-0.44) representing 55.8%, sleep (β = 0.03, 95%CI = 0.0032-0.0575) suggesting 4.0%, and anxiety→sleep (β = 0.013, 95%CI = 0.0024-0.0265) yielding 2.0% of the total effect. Conclusions: Food insecurity was positively associated with depression. This association was partially and serially explained by generalized anxiety and sleep problems. Efforts to address depression among single parents should consider interventions for food insecurity and psychosocial problems, particularly in LMICs. [ABSTRACT FROM AUTHOR]

A growing number of studies suggest that individuals can develop long‐term foraging specializations independently of phenotypic or environmental variation, yet little is known about how the foraging niche is acquired. The early learning of the foraging niche hypothesis suggests a key role of vertical cultural transmission in shaping the foraging niche of vertebrates. In birds, direct evidence from natural conditions is limited to a single study that cross‐fostered two related species. To date, no study has tested whether the diet received as an offspring determines the diet delivered as a parent within a single species. We tested the early learning of the foraging niche hypothesis using a Mediterranean population of great tits Parus major, which show great diet variability and moderate consistency in the diet they provide to their offspring across years. To do this, we recorded prey delivered to 9–14 day‐old chicks over twelve years. Then we assessed vertical transmission of dietary specialization using data (percentage of caterpillars, spiders, and other prey types, as well as mean prey size) from individuals recorded as a chick and as an adult. We standardised the data to control for environmental factors and ran a Linear Model for each prey type to measure individuals' consistency within the group (relative consistency), correlating the diet they received as a chick and the one they provided to their own chicks at the adult stage. The correlations between the diet received as a chick and the diet provided as a parent were either not significant or negative. Hence, although individuals showed relatively consistent foraging niches across years regarding their parental provisioning behaviour, these diet preferences were not correlated to the diet they received in the nest. Further research is needed to determine whether the foraging niche is acquired during the post‐fledgling stage. [ABSTRACT FROM AUTHOR]

Background: The detection of uniparental disomies (the inheritance of both chromosome homologues from a single parent, UPDs) is not part of most standard or commercial NGS-pipelines in human genetics and thus a common gap in NGS diagnostics. To address this we developed a tool for UPD-detection based on panel or exome data which is easy to use and publicly available. Results: The app is freely available at https://altafplotter.uni-leipzig.de/ and implemented in Python, using the Streamlit framework for data science web apps. It utilizes bcftools and tabix for processing vcf files. The source code is available at https://github.com/HUGLeipzig/altafplotter and can be used to host your own instance of the tool. Conclusion: We believe the app to be a great benefit for research and diagnostic labs, which struggle identifying and interpreting UPDs in their NGS diagnostic setup. The information provided allows a quick interpretation of the results and thus is suitable for usage in a high throughput manner by clinicians and biologists. [ABSTRACT FROM AUTHOR]

This paper explores the relationships between low‐income single mothers and their adolescent and early adult children utilizing qualitative interview and focus group data with youth from three Canadian cities. The research explored youth provisioning roles in these families. Provisioning, a concept widely understood in the global south, refers to labour used to sustain low‐income families and includes emotional labour, care work, trade and exchange and paid labour. Findings from this study identified strong expressions of positive attachment and close relationships between youth and their family members. The paper queries whether positive attachment may be built through roles where youth see themselves as integral parts of a family team and where their contributions are acknowledged. These findings invite us to explore and perhaps challenge the oft‐reported correlations between living in a low‐income, lone mother‐led family and poor childhood outcomes and poor attachment. Can these outcomes be mediated and can the provisioning roles youth undertake possibly be such mediators? [ABSTRACT FROM AUTHOR]

We present a paradigm for access control to typed objects logically connected to form a hierarchy, whereby each object has a single parent, and may have children. Protection domains are divided into three classes. A vertical domain includes authorizations for the objects in a subhierarchy. A horizontal domain includes authorizations for the children of a given object. A simple domain includes an authorization for a single object. We introduce the hierarchical capability concept as a generalization of the classical password capability concept. A hierarchical capability references an entire domain instead of a single object.

This study examines whether and to what extent the availability of grandparents in the home plays a buffering role in the labor supply of parents of children aged 0–5 during the COVID-19 pandemic. The role of grandparents as a childcare resource and its association with parents' labor supply have received increasing attention in the literature. Limited childcare options during the pandemic underscore the need to investigate how working parents manage the double burden of family and work and what role grandparents could play. I use monthly data from the Current Population Survey (CPS) from January to May 2019 and 2020. Using a propensity score matching method, parents in three-generational households were matched to those in two-generational households. Then, I employ a difference-in-differences approach with propensity score-matched samples. Results show that parents living with grandparents are more likely to have worked last week and worked longer during the pandemic relative to parents in a two-generational household. The effects of the availability of coresident grandparents are more pronounced among single and low-educated parents than their counterparts. Furthermore, mothers and fathers show heterogeneous responses to the presence of grandparents during the pandemic. In conclusion, results highlight that grandparents played a buffering role in mitigating the adverse impact of the pandemic on parental labor supply. This study sheds light on the importance of grandparental care specifically and informal care and home-based care in general. It also provides policy implications for strengthening the childcare system. [ABSTRACT FROM AUTHOR]

Single-parent households have been the interest of policy since the 1990s in the Taiwanese context. As the impacts of the existing support to single-parent households remains unclear, this research is aimed at empirically comparing the distributional effects of policies on two-parent families and single-parent families with children, with the factors of gender, employment status and co-residence of the head of household being taken into account. Using data from Survey of Family Income and Expenditure for the years 1990, 2000, 2010 and 2019, the findings show that the economic gap between two-parent and single-parent families is growing. There have been clear signs of poverty mitigation for two-parent and single-parent families, showing that a general redistributive policy in Taiwan has been pursued to address poverty reduction for all families, but favour single-parent families. Based on the findings, policy suggestions are made regarding how to address single-parent families' financial wellbeing. [ABSTRACT FROM AUTHOR]

The present study examined the profiles of parental perceptions of their child's school adjustment in terms of learning loss and school well-being during the COVID-19 pandemic in Finland. Furthermore, the extent to which the profiles differed with respect to the different children and their family characteristics, as well as their parents' stress about their child's schooling, were examined. Parents (N = 26,313) completed a questionnaire in spring 2021 concerning parental stress and their children's schooling. The five-profile solution was identified using latent profile analysis: (1) slightly-higher-than-average-school-adjustment (n = 8198, 31.2%); (2) high-school-adjustment (n = 3017, 11.5%); (3) slightly-lower-than-average-school-adjustment (n = 5025, 19.1%); (4) low-school-adjustment (n = 6777, 25.7%); and (5) mixed-school-adjustment (n = 3296, 12.5%). The low-school-adjustment profile was overrepresented among parents of boys, older children, and children with special education needs as well as among parents with lower education levels, higher numbers of children, and in single-parent households. In addition, the results showed that parental stress about their child's schooling was associated with their perceptions of their child's school adjustment during the COVID-19 pandemic. Overall, the results demonstrate that parents' views of their children's school adjustment varied widely during the COVID-19 pandemic. At schools, particular attention should be given to at-risk families (e.g., families with low education levels and children with special education needs) in which children may be prone to learning loss and low well-being due to the COVID-19 pandemic.

The current study explored the experiences of families including single mothers of multiple heritage children. Through narrative inquiry, interviews with a small number of single mothers and adult children from multiple heritage families explored how mothers educated their children about their culture and ethnicity and how children integrated cultural identity through their early development. Findings included narratives of mothers, adult children, and dialogues among the family dyads. Themes included Intersectional Cultural Identity, Ethnic Identity Development, Fostering Cultural Identity, and Seeking Belonging. This study contributes to understanding the cultural and ethnic identity formation of multiple heritage individuals and the implications for cultural awareness in working with families with diverse compositions and with multiple heritage members. Some highlights of the study include: the navigation of choices by single mothers in educating children about cultural history representing both sides of their family; children expressed pride in their identity by embracing all parts of their heritage, despite marginalization and discrimination; family relationships with fathers, sibling dynamics, and parenting styles influenced cultural identity development for children.

Background: The living situation of single parents is often characterised by sole responsibility for family and household, problems in reconciling work and family life, and a high risk of poverty. In a comparative perspective with parents in partner households, the health of single mothers and fathers was analysed, considering differences in their social status. Methods: The analyses are based on data from the GEDA studies 2019 – 2023 (7,999 women, 6,402 men). Prevalences for single mothers and fathers and mothers and fathers living in partner households were calculated for self-rated health, chronic diseases, depressive symptoms, smoking and utilisation of professional help for mental health problems. In multivariate models, adjustments were made for income, education, employment status and social support, and interactions with family type were included. Results: Single mothers and fathers show higher prevalences for all health indicators in comparison to parents living in partner households. Also after adjustment, the differences between family types remain significant. The health of single mothers also varies partially with income, employment status and social support. Conclusions: Health promotion measures have to consider that single parents are a heterogeneous group. In addition to strengthening personal skills, policy and setting-based interventions aim to reduce health inequalities.

Introduction: Unpaid care work is mainly performed by women, whose mental health is more affected by caregiving burden and work-family conflict compared to men. COVID-19 containment measures may have exacerbated existing gender inequalities in both unpaid care work and adverse mental health outcomes. This scoping review provides an overview of recent evidence on the impact of COVID-19 containment measures on unpaid care work and mental health for subgroups of caregivers at the intersection of gender and other social differences (e.g., ethnicity, age, class) in Europe. Methods and analysis: Our study was informed and guided by Arksey and O'Malley's methodological framework. We searched six academic databases (Medline, PsycInfo, Scopus, CINAHL, Social Sciences Abstracts, Sociological Abstracts, ASSIA) and hand-searched the reference lists of selected articles to identify relevant peer-reviewed research articles published between 1 March 2020 and 7 September 2022. In addition, we conducted a grey literature search using Google Scholar and a targeted hand search on known international and European websites. We included studies that reported gender-disaggregated results on unpaid care work and mental health in the context of COVID-19 containment measures in Europe. Two reviewers independently screened all abstracts and full texts for eligibility and extracted the relevant data. The results were synthesised narratively. Results and discussion: Our results suggest a greater gender gap in unpaid care work division and, to a lesser extent, in mental health, which is unfavourable towards women and mothers. Despite this, we see a break in the traditional division of childcare, with fathers taking on a greater role in family work, which makes us optimistic about the division of care work in the post-COVID-19 era. This research also shows that among European women, population groups often understudied, such as women who are single parents, disabled or of colour, have the highest increase in unpaid care work and greatest deterioration in wellbeing.

Despite the clear restrictive guidelines about the use of modern handheld devices among children younger than 2 years, parents are seen to extensively use these devices with their infants. However, parents’ perceptions in this regard remain unclear and underexplored especially, in the context of South Asian cultures such as Pakistan. This qualitative study aims to explore parents’ perceptions regarding their infants’ use of mobile devices. Using the purposive sampling technique, 10 couples (i.e. 20 parents) from Pakistan were individually interviewed using a semi-structured interview guide. Parents with at least two children including one infant (0–2 years) were included. Single parents and parents of children with special needs were excluded. Findings revealed parents hold mixed opinions regarding the use of mobile devices. Parents expressed negative outcomes of the use of mobile devices, which were categorized into internalizing problems, emotional problems, social interaction problems, and issues in cognitive processing. They also shared positive perceptions, categorized as learning outcomes, and increased cognitive abilities. Based on their first-time parenting experiences, parents expressed both negative and positive outcomes of the use of MDs with infants. A shift in perception was observed based on their first-time parenting experiences. With increased parenting demands, participants shared constant challenges in limiting the screen time of infants, leading to experiencing negative emotions among parents i.e. guilt and worry. This study can be useful among clinicians to consider the effects of the use of mobile devices while making a neurodevelopmental diagnosis. It can also be useful in promoting learning among infants in daycare/childcare centers, in developing parenting manuals, and in developing screen time policies or guidelines. [ABSTRACT FROM AUTHOR]

The scale and cluster development of offshore wind power faces the constraints of high construction cost, limited submarine corridor resources, etc. Under the background of offshore wind power parity development, it is urgent to consider the actual constraints of the project and the impact of project income on the owner, and the construction of offshore public station and the optimal selection of transmission method have become an important measure to reduce the cost and increase the efficiency of offshore wind power. A life-cycle cost model for offshore wind farm cluster grid-connection system planning is constructed to consider the project income, and the offshore public station location and capacity, transmission method, and high-voltage cable selection and path are optimized, which are solved by an improved single parent genetic algorithm and a topology repair strategy based on graph theory. The results show that the proposed planning scheme can effectively improve the life-cycle project income of the grid-connection system and provide technical support for the grid-connection planning of large-scale offshore wind farm clusters.

Whilst discourses of motherhood, such as the 'ethic of care' and intensive parenting are powerful and persuasive, no form of motherhood can be acceptable to all. In this visual autoethnography, researcher generated photographs, excerpts from training logs and personal narrative texts are used to explore some of the underlying discourses and assumptions associated with motherhood and sport from the perspective of a single parent. Employing a poststructural lens the author explores the ways in which she has knowingly negotiated her identity as a single mother and competitive-recreational long distant triathlete. The research places a spotlight on the significant support role that children can play in relation to adult involvement in sport, turning the tables on the existing focus on parent-athlete relationships. The findings provide further evidence of the value of sports clubs in supporting the continued participation of mothers, adding to the research on sport and parenthood and family studies.

Background: Many adults in the United States do not reach the recommended levels of activity needed for health benefits. Single-female caregivers present a unique and vulnerable population that is often less active than their partnered peers or single-male caregivers. Objective: The primary objective of this cross-sectional investigation was to identify the prevalence of physical inactivity in single-family, female-led households and determine differences in personal factors and social characteristics between physically active and not physically active single-female caregivers. A secondary objective was to examine associations among the social characteristic variables and physical inactivity in single-female caregiver households. Finally, we examined the odds single-female caregivers who are physically inactive reported chronic health conditions. Design: Cross-sectional survey design. Methods: We used the 2020 Behavioral Risk Factor Surveillance System (BRFSS) data. Participants were selected based on pre-determined criteria for inclusion. Results: There was a 39.3% prevalence of physical inactivity among single-female caregivers in the sample. Single-female caregivers who were physically inactive had greater odds of having a history of multiple chronic health conditions. Conclusion: Healthcare providers and other community stakeholders should explore existing physical activity promotion strategies to increase physical activity in single-female caregivers. Future research should employ more rigorous, prospective research designs to determine if these chronic conditions and various social characteristics are caused by physical inactivity.

The cost-of-living crisis in the United Kingdom has profoundly affected the mental wellbeing of single parents, compounding economic and psychosocial challenges. This study, through semi-structured online interviews with four female single parents, used thematic analysis to explore how financial burdens, mood fluctuations, sacrifices for children’s needs, and intensified social isolation impacted their mental health. The application of Social Identity Theory demonstrates the exacerbating effects of societal stigmas. The results highlight the need for targeted policies and interventions to alleviate these strains and recommend further research into the intersectionality of gender, ethnicity, and socioeconomic status among single parents.

This is a quantitative study, with a descriptive and correlational design, whose objective was to investigate the relationship between self-esteem and parenting styles, taking Brazilian solo mothers as the target audience. The sample consisted of 41 women-mothers in a single-parent context, the majority from Ceará. The research was published on social networks and participants responded online to the Rosenberg Self-Esteem Scale, the Parenting Styles and Dimensions Questionnaire and the Sociodemographic Questionnaire. The results highlighted maternal overload, insufficient support network and the absence of the male father from the parental dynamics. Regarding parenting styles, the sample made greater use of the democratic style, however, the physical coercion dimension of the authoritarian style obtained a score higher than expected. Finally, the correlation test between the level of self-esteem and parental styles and dimensions indicated a positive and significant correlation only with the regulation dimension of the democratic style.

This study investigates the consumer socialization practices of parents in single versus multi-child and nuclear versus extended families in an emerging market. Previous consumer socialization research has focused primarily on western cultures. We examine parenting in a developing market and suggest that single-child families are more nurturant and maintain greater control of their children's media exposure than multi-child families. The findings indicate that Modal Indian consumer socialization practices may be shifting from an Authoritarian to an Authoritative parental style with greater maternal intervention in media exposure and support for regulating children's advertising. Implications for marketers, consumer educators, and public policy makers are discussed. [ABSTRACT FROM AUTHOR]

Although gender ideologies influence many outcomes, research shows they often fluctuate across the life course. Family structure transitions are one mechanism through which gender ideologies change. Divorced and single adults report more egalitarian ideologies than stably married adults. Little research has examined whether children in these families experience similar gender ideologies. Based on parental role modeling, we would expect children in non-traditional families to exhibit more egalitarian gender ideologies. We examine family structure and youth gender ideologies in two contexts, essentially two case studies: Germany and South Korea. Using Starting Cohort 3—Grade 5 (N = 4,021) and Starting Cohort 4—Grade 9 (N = 9,913) of the Germany National Educational Panel Study (NEPS) and Cohorts 1 (N = 2,844) and 2 (N = 3,449) of the Korea Youth Panel Survey (KYPS), we uncover counterintuitive findings that youth gender ideologies do not vary across family structures. Child gender is the most salient predictor of gender ideologies across contexts. Plain Language Summary: Little research has examined whether children experience more egalitarian or less egalitarian gender based beliefs across various family structures, including step-families, single parent families, and two parent families. Based on parental role modeling, we would expect children in non-traditional families to exhibit more egalitarian gender beliefs. We examine family structure and youth gender ideologies in two contexts: Germany (NEPS) and South Korea (KYPS). Using Starting Cohort 3—Grade 5 (N = 4,021) and Starting Cohort 4—Grade 9 (N = 9,913) of the Germany National Educational Panel Study (NEPS) and Cohorts 1 (N = 2,844) and 2 (N = 3,449) of the Korea Youth Panel Survey (KYPS), we uncover counterintuitive findings that youth gender ideologies do not vary across family structures, but that it is the youth's gender that is the most important predictor of a youth's gender beliefs.

Karoonda-like (CK) carbonaceous chondrites are highly oxidized meteorites, with metal-to-magnetite ratio close to zero. Unlike other carbonaceous chondrites (petrologic type: 1–3), most CK chondrites have undergone thermal metamorphism (550–1270 K) on their parent body with a petrologic type 4 or above. Lines of evidence suggest a genetic relationship between CK chondrites and Vigarano-like (CV) carbonaceous chondrites, which are predominantly type 3. However, observable petrographic distinctions persist between the two groups. Thus, a thorough reevaluation of their geochemical discrepancies is critical to test the CK-CV single parent body hypothesis. Northwest Africa (NWA) 13943, a newly discovered meteorite subjected to intense modification, was classified using scanning electron microscopy and electron microprobe techniques. High-precision measurements of the mass-independent chromium isotope compositions (ε 53 Cr and ε 54 Cr) and the mass-dependent oxygen isotope compositions (δ 17 O and δ 18 O) of NWA 13943 were reported for the first time. Integrating petrological, mineralogical, oxygen, and chromium isotopic data, it is legitimated to infer that CK and CV chondrites may originate from two proximal but distinct isotopic reservoirs within the protoplanetary disk.

Research on multilingualism in the home has approached the family as a fixed unit thus neglecting the dynamic view of the family and its intersection with family language practices. The present study aims to address this gap by focusing on Russian-speaking mothers in Finland who have raised their children bilingually in single-parent as well as in dual-parent families. Russian speakers are the largest minority language group in Finland, and their number is constantly growing. The current study is a contribution to the research on family language practices in the Finnish context. It examines the nexus of shifts in family configurations and language practices and explores how the dynamic changes in family constellations shape language practices in four families. The study reveals that creating new kinships leads to shifts in the language practices of the peripheral family members and that forming voluntary kin can expand heritage language use and enable an overhearer and bystander role for children. Non-residential family members expand the family's linguistic repertoire and support the legitimacy of already established practices. Being sole caretakers enables mothers to encourage language practices that they consider beneficial for their children without encountering any resistance from other family members.

BACKGROUND Disclosure of donor conception has been advocated in several jurisdictions in recent years, especially in those that practice identity-release donation. However, research on disclosure decisions has not been consolidated systematically in the last 10 years to review if parents are telling and what factors may be impacting their decisions. OBJECTIVE AND RATIONALE Are parents disclosing to their donor-conceived children, and what factors have influenced their disclosure decisions across different contexts and family forms in the last 10 years? SEARCH METHODS A bibliographic search of English-language, peer-reviewed journal articles published between 2012 and 2022 from seven databases was undertaken. References cited in included articles were manually scrutinized to identify additional references and references that cited the included articles were also manually searched. Inclusion criteria were articles focused on parents (including heterosexual, single mothers by choice, same-sex couples, and transsexual) of donor-conceived persons in both jurisdictions with or without identity-release provisions. Studies focused solely on surrogacy, donors, donor-conceived persons, or medical/fertility staff were excluded as were studies where it was not possible to extract donor-recipient parents' data separately. Both quantitative and qualitative studies were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and Joanna Briggs Institute Critical Appraisal Tools for Systematic Reviews were used to assess article quality and bias. OUTCOMES Thirty-seven articles met the inclusion criteria representing 34 studies and 4248 parents (including heterosexual, single, same-sex, and transsexual parents although the majority were heterosexual) from countries with anonymous donation and those with identity-release provisions or who had subsequently enacted these provisions (Australia, Belgium, Finland, France, Hong Kong, Middle East, Spain, Sweden, the UK, and the USA) A general trend towards disclosure was noted across these groups of parents with most disclosing to their donor-conceived children before the age of 10 years. Further, the majority of those who had not yet told, reported planning to disclose, although delayed decisions were also associated with lower disclosure overall. Same-sex and single parents were more likely to disclose than heterosexual parents. There was recognition of disclosure as a process involving ongoing conversations and that decisions were impacted by multiple interacting intrapersonal, interpersonal, and external contextual and social factors. Methodological limitations, such as the different population groups and contexts from which participants were drawn (including that those parents who choose not to disclose may be less likely to participate in research), are acknowledged in integrating findings. WIDER IMPLICATIONS This review has reinforced the need for a theoretical model to explain parents' disclosure decisions and research exploring the role of legislative provisions, culture, and donor/family type in decision-making. Greater ongoing access to psychological support around disclosure may be important to promote parent and family well-being. [ABSTRACT FROM AUTHOR]

The COVID‐19 pandemic, as an ongoing societal crisis, compounds pre‐existing intersectional inequalities. Since the start of this crisis, those on the margins—women, single parents, LGBTQ+, Black, Asian, and Minority Ethnic peoples—and those living in precarity and poverty found themselves increasingly "othered." As a group of academics who encounter gendered reality in disparate ways, we unite through this paper to prioritize a collective ethic of care as a counter‐narrative to the "business as usual" rhetoric that endures as our oppressive reality. In responding to this special issue, a (dis)embodied alterethnographical text is offered, encompassing four evocative reflections on symbolic annihilation to "unmute" our individual voices. We present an inclusive discussion to connect our disconnected otherness, collectively resisting the dominant, patriarchal narratives, through non‐linear, "messy writing." Our contribution is threefold. First, we empirically contribute to dismantling heteronormative binarism by reclaiming our collective voices as a loud rebuttal to hegemony. Second, through collective conceptualizations of gendered crisis, we problematize theorizing gender from a unified conceptual lens to demonstrate the importance of an inclusive approach to feminism. Finally, a collective discussion of our cumulative experiences, contributes to the writing differently agenda, subverting the limitations of the encountered gender binaries. [ABSTRACT FROM AUTHOR]

Background: Previous studies have shown that children and adolescents living with single parents are prone to behavioral and psychological difficulties and experience a poor sense of well-being. Also, the period of adolescence is critical for the development of an individual in multiple aspects; it is important to focus on their well-being and associated factors for a better transition into adulthood. Aim: This study aims to find the mediating role of social competence and emotion regulation on the relationship between resilience and psychological well-being among single-parent adolescents. Methods: This was a cross-sectional study. The study sample was 385 adolescents residing in Kerala (179 boys and 206 girls, mean age = 15.03, SD = 1.45). A total of 185 participants (48.1%) were from families that lost either of their parents to death, and the other 200 participants (51.9%) were from divorced or separated families. Self-reported measures for resilience, social competence, emotion regulation, and psychological well-being were used for data collection. Data were analysed using IBM SPSS and AMOS version 24. Results: The results showed that resilience, the prosocial behavior dimension of social competence, and the cognitive reappraisal dimension of emotion regulation indicate significant positive associations with the psychological well-being of adolescents living in single-parent families. The expressive suppression dimension of emotion regulation and the antisocial behavior dimension of social competence have a substantial negative connection with the psychological well-being of adolescents raised by single parents. The findings suggest that resilience directly predicts psychological well-being; prosocial behavior and cognitive reappraisal partially mediate the association of resilience and psychological well-being. Conclusion: According to our findings in this study, developing social competence skills and adaptive emotion regulation strategies can improve the psychological well-being of adolescents living with single parents. The results have multiple clinical, educational, and community implications. [ABSTRACT FROM AUTHOR]

Background: Single parenthood is becoming increasingly common in today's society for various reasons such as divorce, the death of a spouse, or the choice of parenthood. Regrettably, there seems to be no significant concern among world leaders regarding depression arising from single parenting. Aim: This article aimed to explore the prevalence of depression in single parents, the factors contributing to it, and its effects on their physical and emotional well‐being. Additionally, it aims to investigate the long‐lasting effects of depression in single parents, effective therapeutic approaches to tackle these issues and offer proactive suggestions for relevant global stakeholders. Methodology: A selection of studies was identified through electronic databases such as PubMed, Embase, and PsycINFO databases. The search strategy encompassed terms related to single parenthood, depression, mental health, prevalence, risk factors, and treatment modalities. Included studies comprised of peer‐reviewed research articles, systematic reviews, meta‐analyses, and observational studies published in English. Result: Today, there is a growing prevalence of single parenthood due to a range of factors, including divorce, the loss of a partner, and intentional decisions regarding single parenthood. However, this transition comes with challenges, including the risk of developing depression. Depression is a serious mental health condition affecting many individuals worldwide. Raising a child alone increases the likelihood of developing depression for the parent due to the increased burden and responsibilities. Such parents tend to have low self‐esteem, suicide/suicide attempts, and so forth and children born by those parents are vulnerable to depression, physical abuse, infections, etc. Conclusion: Future research should focus on identifying effective interventions for treating depression among single parents and improving the availability of mental health facilities for this vulnerable population, especially in places with a high prevalence of depression. Mental health physicians in collaboration with obstetricians and gynecologists across the globe should offer counseling and mediation services during pre‐conception care visits for both single and partnered parents.

In the United Kingdom, the COVID-19 pandemic in 2020 and 2021 led to two extended periods of school closures. Research on inequality of learning opportunity as a result of these closures used a single indicator of socio-economic status, neglecting important determinants of remote learning. Using data from the Understanding Society (USoc) COVID-19 surveys we analysed the levels and differentials in the uptake of remote schoolwork using parental social class, information technology (IT) availability in the home and parental working patterns to capture the distinct resources that families needed to complete remote schoolwork. This is also the first study to assess the extent to which the differentials between socio-economic groups changed between the first and second school-closure periods caused by the pandemic. We found that each of the three factors showed an independent association with the volume of remote schoolwork and that their effect was magnified by their combination. Children in families where the main parent was in an upper-class occupation, where both parents worked from home and where the children had their own IT spent more time doing remote schoolwork than other groups, particularly compared to children of single parents who work from home, children in families where the main parent was in a working-class occupation, where the child had to share IT, and where the parents did not work regularly from home. The differentials between socio-economic groups in the uptake of schoolwork were found to be stable between the two school-closure periods. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to implement a child abuse prevention program and evaluate its effectiveness based on the Nursing Model of Resilience and Coping Skills Training Model for unmarried mothers during pregnancy and puerperium. Methods: This study had a prospective single-case, AB design with four repeated self-questionnaire measures and three observational measures. Seven unmarried mothers were provided with 10 sessions child abuse prevention program through individual visits from 32 to 34 weeks of pregnancy to six weeks after childbirth. The questionnaire was composed related to resilience, maternal stress, maternal attitude, parent-child interaction, child abuse potential. The observation was measured by video recording (total 16 times) the interaction of parent-child during feeding and analyzing it by three experts. Data were analyzed by Wilcoxon signed-rank test and Friedman's test. Results: Maternal attitude and parent-child interaction were statistically significantly improved after intervention compared to before intervention. However, maternal stress decreased after intervention compared to before intervention, but it was not statistically significant. Additionally, resilience and child abuse potential were not statistically significant. This program is partially effective in preventing child abuse by promoting parenting attitudes and parent-child interactions. Conclusion: This study focused on individual resilience and applied systematic intervention as coping skills training to prevent child abuse. This study is meaningful in that interventions were conducted through individual visits to unmarried mothers at high risk of child abuse, and the program was applied, including pregnancy and postpartum periods, to prevent child abuse early.

The widespread ability of proteins and peptides to self‐assemble by forming cross‐β structure is one of the most significant discoveries in structural biology. Intriguingly, the cross‐β association of proteins/peptides may generate intricate supramolecular architectures with uncommon spectroscopic properties. We have recently characterized self‐assembled peptides extracted from the PREP1 protein that are endowed with interesting structural/spectroscopic properties. We here demonstrate that the green fluorescence emission of the peptide PREP1[117‐132] (λem ~520 nm), can be induced by excitation with UV radiation. The associated unusually large Stokes shift (Δλ ~150 nm) represents, to the best of our knowledge, the first evidence of an internal resonance energy transfer in amyloid‐like structures, where the blue emission of some assemblies becomes the excitation radiation for others. Moreover, the characterization of PREP1[117‐132] variants provides insights into the sequence/structure and structure/spectroscopic properties relationships. Our data suggests that the green fluorescence is plausibly associated with antiparallel β‐sheet states of the peptide whereas parallel β‐sheet assemblies are only endowed with blue fluorescence. Notably, the different PREP1[117‐132] variants also form assemblies characterized by distinct morphologies. Indeed, the parent peptide and single mutants form compact but structured aggregates whereas most of the double mutants exhibit elongated and highly extended fibers. [ABSTRACT FROM AUTHOR]
