Hormones play an important role in the development and regulation of reproductive function and the menstrual cycle of women. Extremes of body weight tend to affect the homeostasis of the hypothalamo–pituitary–gonadal axis. This cross-sectional study was carried out in 113 women (57 with primary infertility and 56 with secondary infertility) in the age group 20–35 years, presenting for hormonal evaluation of infertility in a tertiary care hospital. After preliminary clinical evaluation, anthropometric indices (height, weight, BMI, waist circumference and waist hip ratio) were measured in all subjects. Fasting blood sample drawn on second/third day of menstrual cycle was analysed for serum luteinizing hormone, follicle stimulating hormone (FSH), prolactin and thyroid stimulating hormone (TSH). Serum FSH levels showed a significant positive correlation with indicators of central obesity (waist circumference and waist hip ratio in both the study groups). In primary infertility, significant positive correlation was also observed between serum FSH levels and other markers of obesity like body weight, hip circumference and BMI. In secondary infertility, serum prolactin and serum TSH levels demonstrated a significant positive correlation with body weight and BMI. Obesity is associated with hormonal derangements which are responsible for infertility. In overweight women with infertility, weight loss should be considered as a first line treatment.  相似文献

This systematic review offers an overview of the results of research from the last 10 years concerning the teacher-student relationship and its connection with other attachment theory constructs and child development variables. An exhaustive search of Web of Science, SCOPUS, and PsycINFO was performed, finding a total of 24 studies that met the established eligibility criteria. The evidence accumulated between 2010 and 2020 suggests that: 1) early care experiences have an effect on the formation of new relationships at primary school, although it is possible that children will construct new mental representations based on interactions in day to day life, 2) at the level of the teacher's characteristics, attachment style and the availability towards children's needs seem to be associated with school adjustment and problematic behaviour in children, and 3) the quality of the teacher-student relationship is significantly associated with externalizing and internalizing behaviour, school liking, peer acceptance, academic performance, self-concept and emotional regulation in children. For its part, when evaluating the quality of the teacher-student relationship, STRS continues to be widely used to study the teacher's perspective. However, in recent years other measurement instruments have become available that explore the perspective of the student, most notably CARTS and SPARTS. Advances in the study of the teacher-student relationship as a bond with important implications for the development of children in the primary education stage are discussed.  相似文献

游戏一直是体育比赛的最初形式。根据文献资料,可以从逻辑分析、运动生理学及运动训练学说的角度,对于中小学体育教育的特点、分类、功能及课程安排进行系统分析,结果显示:体育游戏为中小学体课堂中不可或缺的手段以及内容,它具有一定的趣味性,加之规则的严密性、全面性和可变性等诸多功能和特点,应该根据中小学生肌肉骨骼的特征、心肺功能、神经系统特征及个人体质的差异,合理充分地安排运动量,并掌握好活动及修整时间,采用形象而又生机有趣的游戏内容,促进上课的积极性。  相似文献

随着课程改革的不断深入,选项教学成为体育教学模式改革的重要内容。选项教学打破了传统的体育课教学模式,由"要我学"向"我要学"的方式转变,使体育课教学发生了可喜的变化。其中,身体素质的提高和运动基本技术的普及是实施选项教学的前提条件,选好教学内容是实施选项教学的核心,组织实施是实施选项教学的关键,选用教学方法是实施选项教学的保障。  相似文献

A key goal of home visiting is to connect children with medical homes through anticipatory guidance regarding recommended well child care (WCC). Substantial barriers to WCC among low socioeconomic families can limit achievement of this outcome. Quality improvement strategies have been widely adopted in healthcare but only recently implemented in home visiting to achieve program outcomes. The objective of this initiative was to increase the percentage of infants enrolled in home visiting who completed at least 3 recommended WCC visits in the first 6 months of life within a large, multi-model program comprised of 11 sites. A series of 33 quality improvement cycles were conducted at 3 sites involving 18 home visitors and 139 families with infants in the target age range. These were deployed sequentially, and changes within and across sites were monitored using trend charts over time. Adopted strategies were then implemented program-wide. Initiatives focused on staff training in WCC recommendations, data collection processes, monthly family tracking reports, and enhanced communication with primary care offices. Data were shared in iterative sessions to identify methods for improving adherence. Wide baseline variability across sites was observed, with the percentage of infants with recommended care ranging from 35% to 83%. Over the project timeline, the percentage of infants receiving at least 3 WCC visits in the first 6 months increased from 58% to 86%. Quality improvement within home visiting can be used to improve WCC adherence and provides an example of maximizing implementation of home visiting interventions.  相似文献

This interview study, including seven case studies of mentor teachers in primary education, explores the possibilities and challenges these mentor teachers perceive when they (sequentially and simultaneously) combine the teacher and mentor roles. Mentor teachers perceive two challenges while simultaneously performing both roles in the same classroom: to transfer (or not) responsibility for the class and pupils to the student teacher and to intervene (or not) in classroom procedures. Mentor teachers felt that being the teacher of the pupils was their primary task, and being a mentor of the student teacher generally was perceived as an aside and additional task.  相似文献

In mathematical word problem solving, a relatively well-established finding is that more errors are made on word problems in which the relational keyword is inconsistent instead of consistent with the required arithmetic operation. This study aimed at reducing this consistency effect. Children solved a set of compare word problems before and after receiving a verbal instruction focusing on the consistency effect (or a control verbal instruction). Additionally, we explored potential transfer of the verbal instruction to word problems containing other relational keywords (e.g., larger/smaller than) than those in the verbal instruction (e.g., more/less than). Results showed a significant pretest-to posttest reduction of the consistency effect (but also an unexpected decrement on marked consistent problems) after the experimental verbal instruction but not after the control verbal instruction. No significant effects were found regarding transfer. It is concluded that our verbal instruction was useful for reducing the consistency effect, but future research should address how this benefit can be maintained without hampering performance on marked consistent problems.  相似文献

一线教师和校长对新入职教师的素质如何评价,对师范院校培养高素质的教师有何建议?这对师范院校更好地培养未来教师尤为重要。针对中部六省中小学教师"关于师范生素质现状"的调查表明:中小学教师认为从师范院校毕业的新任教师在新的教育理念、现代教育技术、学科专业知识方面和教育科学知识方面占有很大的优势;而在课堂管理能力、敬业精神、课堂知识落实意识与落实能力、处理师生关系能力、课程标准意识等方面存在明显不足。当前教师教育要加强学生教育教学实践能力的培养,师范院校要增加学生下基层,到教学一线实习的机会,同时要注重对学生实习过程的监管,提高学生实习的质量;师范院校要注重师范生职业道德修养的培养,特别是对未来教师敬业精神的培养。  相似文献

2009年开始开展的“校园足球”活动是我国发展青少年足球运动的重要途径和举措。为了了解四川省校园足球活动的开展情况,研究选择了四川省首批校园足球布点城市-达州市为调查对象,调查发现“校园足球”活动到目前为止并未取得较为显著的成果,具体表现在足球项目并不是中小学生参与运动的首选项目;中小学开设足球课程的比例较低;布点学校和非布点学校对于足球运动的重视程度差别不大;“校园足球”活动开展以来达州市整体参与足球运动的青少年人数并未显著增加。  相似文献
