The impact of coworker support and stigma on breastfeeding after returning to work

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.

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

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.     

基于用户兴趣度量的知识发现服务精准推荐

[目的/意义]针对当前知识发现服务中存在的个性化程度不高和推荐效果不佳等问题，提出一种基于用户兴趣度量和内容分析的推荐算法。[方法/过程]文章通过特征词分布、LDA主题分布、引文结构网络三个维度构建学术资源模型，并通过对用户行为的度量，计算用户对其浏览学术资源的兴趣度，结合学术资源模型构建用户兴趣模型。将用户兴趣模型与学术资源模型匹配，计算其相似度，得到用户对每条学术资源的兴趣值，最后将兴趣值最高的TOP-N学术资源推荐给用户。[结果/结论]通过实验检验算法的有效性和推荐准确率，结果显示，本文从实时动态度量兴趣的角度，提出的推荐算法能较好地预测用户兴趣，推荐效果显著，为实现发现服务精准推荐提供思路。     

大学物理教育的统计调查及分析

以陕西师范大学物理学院四个班级和渭南师范学院化学化工系三个班级为调查对象,以电子计算机为计算工具,采用数学模型对数据进行处理,以定量研究的结果对大学物理教育的实际情况作了初步分析:(1)中学知识水平是影响普通物理教学的基本因素,且中学的数学和物理知识水平对普通物理教学影响显著;(2)大学物理近代物理部分相关远大于经典物理部分,其中热学、光学对普通物理教学影响显著.     

论大学教师的人格风范

高等教育是推动社会发展与进步的重要智力工程 ,担负着为社会培养高素质人才、创造民族未来的崇高历史使命。作为高校崇高使命的具体承担者 ,大学教师的思想道德素养和人格风范 ,无疑是影响和制约高校践履自己崇高使命的关键性因素。因此 ,对该问题进行深入的研究和探讨 ,就具有了超越大学教师队伍建设本身的深远的社会意义。　　 (一 )大学教师人格风范的主要特征1 在人格风范的意识水平上 ,具有明显的高层次特征。从历史上看 ,任何一个时代的教育 ,总是首先要完成对人类文化的历史继承 ,同时实现当代文明的整合 ,并由新的一代承接和发展…
