This study assessed the impact of coworker support on lactating mothers’ breastfeeding self-efficacy after maternity leave. A cross-sectional survey of 1000 working adults assessed effects of perception of fairness, coworkers’ support for breastfeeding colleagues, and ick response on willingness to help mothers needing breaks to pump breastmilk at work. The study also examined how coworker support affected mothers’ self-efficacy to continue breastfeeding. One out of four coworkers showed moderate to strong stigma, saw breaks to pump breastmilk as unfair, and showed less intention to help new mothers. These results suggest that while the majority of coworkers are generally supportive, lactating women are likely to encounter disapproving coworkers who may discourage them from continuing to breastfeed. The data showed that the majority of organizations included in this study have only passively fostered mother-friendly workplaces and could do more to encourage employees to be supportive of lactating colleagues.  相似文献

我国大学生五人制足球2015-2016年度总决赛进球分析     

吴建喜  陈艳  李欣  胡杰  李可可 《北京体育大学学报》2017,40(2):112-117

摘要：以参加2015-2016特步中国大学生五人制足球联赛总决赛的8支队伍在小组赛及淘汰赛20场比赛中的 191个进球为研究对象，通过文献资料法、技术统计法以及访谈法对这191个进球时段、进球动作、进球方式、进球场地位置、球入球门的区域进行了分析。主要结论：进球数最多的时段分别是在上半场开局5 min内和在下半场最后5min、进球数最多技术动作是正脚背抽射技术、进攻方式中快攻战术贡献率最大、进球数最多的场地区域是球门前的区域、球入球门的区域中下路明显多于中路进球数。建议在赛前分析对手进攻和防守战术及特点并布置有针对性的战略战术，为良好的开局奠定基础；加强个人运球突破能力的训练；加强两三个人之间的传切配合、策应配合训练，尤其提高定位球的战术配合能力。  相似文献   

城市化进程中的中国体育现状研究     

邱雪 《北京体育大学学报》2017,40(2):10-16

摘要：城市化是国家经济制度、政治体制和社会形态发生变革的重要引擎，在体育领域，城市化进程的结束则标志着体育发展方式的重要转型。有鉴于此，以我国城市化进程中的体育发展现状为研究对象，主要采用文献资料法和比较分析法，结合英、美2国的实例，详细梳理城市化进程结束后，即城市化水平达到50%背景下，城市化对我国体育人口规模、体育空间布局、体育产业结构以及体育管理体制所造成的影响，其研究结果对于厘清现阶段我国体育发展的症结及未来我国体育改革的对策均具有重要的理论意义及实践价值。研究认为：城市化作为一种人类社会发展的普遍规律，始终影响着体育发展的进程与走向；城市化水平与体育发展的现实水平存在着高度的相关性，当城市化水平达到50%的时候，标志着体育将进入到一个全面转型的发展时期；我国已经进入到城市化进程过半的关键时期，城市化对体育发展方式的影响已经全方位体现出来，城市化引致的人口聚集成为了体育人口发展的基础，城市化引发的城市扩张导致了体育空间布局的整合，城市化催生的结构调整搭建了体育产业发展的平台，城市化激发的制度改革完善了管理体制发展的模式。  相似文献   

Precision measurement of the Newtonian gravitational constant     

Chao Xue  Jian-Ping Liu  Qing Li  Jun-Fei Wu  Shan-Qing Yang  Qi Liu  Cheng-Gang Shao  Liang-Cheng Tu  Zhong-Kun Hu  Jun Luo 《国家科学评论(英文版)》2020,7(12):1803

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.  相似文献   

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication     

Shoudong Wang  Shulin Liu  Jie Wang  Kengo Yokosho  Bin Zhou  Ya-Chi Yu  Zhi Liu  Wolf B Frommer  Jian Feng Ma  Li-Qing Chen  Yuefeng Guan  Huixia Shou  Zhixi Tian 《国家科学评论(英文版)》2020,7(11):1776

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.  相似文献
