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 paper examines the reasons why long‐serving teachers remain in the teaching profession. Interest in teacher retention has grown in recent years, both in the UK and internationally, due to concerns over teacher shortage. However, most research on retention has focused on why teachers leave; this paper aims to fill the gap in our understanding of the positive reasons why long‐serving teachers stay in the profession, and how these reasons change over time. We define ‘long‐serving teachers’ as teachers who have taught for 10 years and more. We draw on a subset of data from an existing, broader study (Menzies et al., 2015 ) on why teachers enter and stay in the profession. In this paper, we draw on questionnaire findings from over 900 teachers with 0 to over 30 years’ teaching experience, and interviews with 14 long‐serving teachers, to understand why long‐serving teachers enter and, more importantly for our purposes, stay in teaching. We find that teachers’ motivational patterns are highly complex and influenced by school‐level and policy contexts. Nonetheless, two prominent retention factors are identified: teachers’ perceived professional mastery and altruistic reasons. Perceived professional mastery is particularly important due to its mutually reinforcing analytic relationships with other reasons. We find that teachers’ identification with intrinsic, altruistic and perceived professional mastery reasons become stronger with years of experience, but in some cases, paradoxically, so does their identification with extrinsic reasons. From our evidence, we suggest policy implications for enhancing the retention of long‐serving teachers. 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

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

Putative Role of Cardio Metabolic Risk Among Poorly Controlled Asthmatics in South Indian Population
Murugaiyan Sathish Babu K. P. Sreesoorya Surendra K. Menon Subiman Saha A. R. Srinivasan S. Arul Vijaya Vani R. Reeta V. Kuzhandai Velu 《Indian journal of clinical biochemistry : IJCB》2017,32(2):225-229
Mortality and morbidity attributed to asthma remains to be the biggest nightmare worldwide. Hence, the study was aimed to compare the cardio metabolic risk factors as assessed by Body mass index (BMI), waist hip ratio (WHR), serum triacylglycerol and uric acid in well controlled and poorly controlled asthmatics and to correlate these parameters with the severity of asthma. A case control study was conducted on 90 subjects who were segregated into well controlled asthmatics (n = 30) and poorly controlled asthmatics (n = 30) who were diagnosed based on Global initiative for Asthma management guidelines and healthy volunteers (n = 30). Centrifuged fasting venous blood samples were used for biochemical analysis, pulmonary function test, BMI, and waist hip ratio (WHR) were measured. The statistical analysis was done using SPSS version 17. There was a significant increase in BMI, WHR, lipid profile, serum uric acid and decrease in forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC in poorly controlled asthmatics. There was a significant association between FEV1 and serum uric acid, BMI and Triacylgycerol in poorly controlled asthmatics. Poorly controlled asthmatics have greater risk of developing cardiometabolic problems. Serum uric acid can be used as one of the severity markers in asthma to assess cardio metabolic risk. 相似文献

HIV infects cluster of differentiation 4 (CD4) T-lymphocytes, monocytes and macrophages resulting in decreased number and function of CD4 cells, changes that affect both cell mediated and humoral immunity. Hematological abnormalities are a common complication of human immune virus (HIV) infection and these abnormalities increase as the disease advances. Anemia is the most common haematological abnormality in HIV seropositive patients and its incidence is strongly associated with the progression of the disease. The aim of present study was to assess the haematological profile of HIV seropositive women and compare them with CD4 count. Two hundred seropositive females (age 18–25 years) attending antiretroviral therapy clinic were selected. Routine gynaecological and haematological investigations were carried out, study samples were drawn and serum iron, folate and ferritin were analysed by chemiluminiscence and CD4 count was determined by using flow-cytometry. Anemia was prevalent in seropositive women especially in those with low CD4 levels. Serum folate and ferritin levels were significantly lower in females with lower CD4 levels. Serum iron levels were higher at low CD4 levels. The mean CD4 count in HIV seropositive anaemic women were lower as compared to non anaemics suggesting that anaemia improves with higher CD4 cell counts. Plasma folate and ferritin levels are sensitive predictor of anaemia in early HIV infections and these patients should have a regular monitoring of their folate and ferritin levels especially with lower CD4 levels. 相似文献
