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。

<中图法>4版个人著作集归类问题

通过一系列的实例分析，指出《中国图书馆分类法》4版个人著作集归类中存在的一些问题，并提出：“党的领导人”类目范围应扩大到对党的建立和发展起过重大作用的领导人；关于历史人物政治理论方面的个人著作集应归属于当时的政治制度史；对于跨学科、综合性的个人著作集，社会科学内容的入C类，自然科学内容的入N类，只有横跨C、N两大类内容的才入Z类等。     

信息生态视角下社会网络伦理规约模型构建研究

[目的/意义]社会网络伦理作为社会网络信息活动中产生的新型伦理,其规约模型的构建较为清晰地描述如何规约信息人、信息技术、社会网络环境,从而为处理社会网络伦理缺失行为提供指导。[方法/过程]明确网络伦理的主体关系和研究范畴,基于信息生态的构成要素,阐释社会网络伦理的概念内涵。在对社会网络伦理作用机理进行分析的基础上,认为网络伦理缺失行为的主体根源即信息人的责任意识,以责任伦理为理论切入点,构建社会网络伦理规约模型。以“魏则西事件”为例,阐释社会网络伦理规约模型与该事件监管思想的契合度,最后提出基于社会协同的网络伦理规约实施策略。[结果/结论]建构社会网络伦理规约的理论框架,提出基于社会协同的网络伦理规约实施策略,对于引导和规范网络信息活动具有重要作用。
