SYNOPSIS
Objective . Most parents manage some degree of parenting stress without serious concerns, but young mothers experience parenting stress at higher levels than adult mothers; high parenting stress is problematic due to its association with children’s socioemotional and behavior problems and the increased likelihood of maltreatment. Understanding the circumstances that precipitate or mitigate parents’ stress can have lasting impacts for child well-being. Extant research fails to account for both longitudinal and individual variation in young mothers’ parenting stress, leading to equivocal findings about the nature of mothers’ parenting stress trajectories across early childhood. Design . The present study used growth mixture modeling (GMM) to model the trajectories of 544 first-time young mothers’ parenting stress from children’s infancy to school-age. We considered how protective factors (i.e., social support) and psychological vulnerabilities (i.e., depression) experienced during the transition to parenthood were associated with parenting stress trajectories and variation within trajectories when children were of school-age. Results . GMM identified three trajectories of parenting stress: “low stable”, “high increasing”, and “high decreasing.” Protective factors were related to low and decreasing patterns of parenting stress, whereas psychological vulnerabilities were associated with higher parenting stress patterns. Conclusions . This study has implications for programs and services that help young mothers cope with the demands of parenting and reduce parenting stress. 相似文献

PCOS is a heterogeneous endocrine disorder with diverse clinical presentation. Oxidative stress plays a key role in the pathophysiology of this disease. Serumhigh sensitive C-reactive protein (hsCRP), a marker of chronic low grade inflammation, is indicative of future development of cardiovascular disease. Our aim is to evaluate the oxidant status and hsCRP levels in PCOS. The study involved 61 cases and 61 controls in the age group of 18–40 years diagnosed with PCOS. Erythrocyte malondialdehyde (MDA), superoxide dismutase (SOD), serum hsCRP, gonadotrophins, thyroid stimulating hormone, prolactin, glycemic status and lipid profile were estimated. Erythrocyte MDA (p < 0.001), SOD (p = 0.007) and serum hsCRP (p < 0.001) were significantly elevated in PCOS patients than controls. Oxidative stress is present in women with PCOS along with elevated hsCRP. 相似文献

This study evaluated the hypothesis that self-perceived gender nonconformity is distressing to children because it undermines a confident sense of gender compatibility. Participants were 357 early adolescents (180 boys, M age = 12.68 years) in England who responded to questionnaires measuring friendship styles (preoccupied, avoidant), gender compatibility (typicality, contentedness), and adjustment (self-esteem, peer social competence, depression, narcissism). Sex differences in friendship styles indicated that preoccupied and avoidant styles were typical for girls and boys, respectively. Gender-atypical friendship styles predicted poor adjustment, and their impact on adjustment was partially mediated by felt gender compatibility. Results suggest that perceiving gender-atypical attributes in the self undermines adjustment partly because it leads children to feel incompatible with their gender collective. 相似文献

The purpose of this study is to explore the South Korean government's policy objectives for the Broadband Convergence Network (BcN) between 2004 and 2007. The BcN is envisioned as conduit for broadband content and applications. This paper uses generativity as a conceptual framework to determine whether the objectives for the BcN, based on a content analysis of policy documents and interviews with experts, empowered the network to sustain a generative critical information infrastructure. This study is designed to be useful for executives in the private sector, officials in government and academics in university settings who are interested in drawing insights from Korean experience to inform their own work. 相似文献

Social media has transformed the communication landscape for institutions of Higher Education by providing improved teaching and learning experience. However, very little is known as to whether the use of social media by Higher Education students improves their satisfaction. Grounded in social media, risk and technology acceptance literature, this paper examines Higher Education students' perceptions of social media use (SMU) and the impact of SMU on their satisfaction. Data collected from the students were analysed using Structural Equation Modelling. The study finds that: (1) perceived usefulness of social media has positive effect on the use of social media in student learning; (2) perceived risk of using social media discourages the use of the tool, and (3) SMU has positive effect on student satisfaction. The study further discusses the theoretical and practical implications of these findings. 相似文献

Eleven Grade 6 students from a class of 26 Canadian children (comprising both Grade 5 and Grade 6 students) were the focus of a 15-week study on students' mathematical learning through writing, where Student Journals (SJ) and Student-Constructed Questions (SCQ) were used by the class teacher as an integral part of her lessons on common and decimal fractions. Student interviews, classroom observations and a teacher interview complemented the analysis of SJ and SCQ. Both writing tasks evidenced students' mathematical learning, but while the SCQ indicated students' fraction knowledge more clearly, the SJ did not communicate students' understanding of fractions as well as student's verbal discussion and explanations did. 相似文献

The present paper attempts to assess the link between economic factors and the private demand for higher education through an investigation of the findings of relevant studies. After an examination of the various methodologies adopted by different authors in the estimation of the perceived rate of return to higher education, the main findings of available studies conducted in several countries (UK, the Philippines, Egypt, Hong Kong, and Cyprus) are discussed and compared. The main conclusions drawn from this comparison are the following: First, the perceived rates of return to higher education are, for the most part, very realistic, indicating an accurate perception of the economic benefits of higher education on the part of students. Second, non‐economic factors, such as gender, ability and socio‐economic background, appear to constitute strong influences on the private demand for higher education, which educational policy makers should take into account, along with the economic variables. Finally, it is suggested that the methodology discussed in the present paper can be used in the future to estimate the perceived profitability of higher studies at different institutions and countries offering higher education. 相似文献

The study was designed to evaluate the hepatoprotective activity of ethanolic extract of Bacopa monnieri in acute experimental liver injury induced by Nitrobenzene in rats. The extract at the dose of 200 mg/kg body weight was
administered orally once every day for 10 days. The increased serum marker enzymes, Aspartate transaminase, Alanine transaminase
and alkaline phosphatase were restored towards normalization significantly by the extract. Significant increase in SOD, CAT
and GPx was observed in extract treated liver injured experimental rats. Histopathological examination of the liver tissues
supported the hepatoprotection. It is concluded that the ethanolic extract of Bacopa monieri plant possess good hepatoprotective activity. 相似文献
