人口政策是国家基于对当前和未来人口增长判断而实施的政策,深受生育率的影响。中国、日本、印度、加纳和法国这几个国家的生育率变化和人口政策流变的案例研究,体现了生育率与人口政策之间的复杂动态关系。研究发现,生育率的变化会刺激人口政策的调整,而人口政策也会对生育率产生影响,两者呈现出双向关联的特点。具体而言,抑制生育的人口政策作用明显而稳健,而刺激生育的人口政策与生育水平之间并没有一致性的正相关关系。理顺底层逻辑、尊重个体意识的人口政策对生育率有积极影响,而底层逻辑不通、模糊个人角色定位的人口政策对生育率的提升作用则不甚明显。这些结论为我国人口政策的制定提供了重要的理论和实践启示。

人口老龄化是21世纪全球面临的共同挑战。从生产性老龄化的视角来看,当前南京市时间银行在社区互助养老中存在着低龄老人参与积极性不足、社区对于“时间银行”的宣传不足、“时间银行”通存通兑难等问题。对此,提出时间银行社区互助养老的发展对策:弘扬生产性老龄化理念,重视老龄生产力价值;建立合理表彰奖励制度,开发老年人力资源禀赋;加强信息数据库建设,促进时间银行跨区通兑。

目的:研究添加富含乳脂肪球膜(MFGM)乳清蛋白粉(M-WPI)前、后的保加利亚乳杆菌发酵乳中保加利亚乳杆菌存活率,发酵乳风味及抗氧化能力。采用代谢组学分析添加M-WPI前、后保加利亚乳杆菌发酵乳的显著差异代谢标志物及其作用通路。方法:通过样本主成分分析、偏最小二乘判别分析、热图分析和KEGG富集分析等方法确定加入M-WPI前、后发酵乳代谢过程中的差异性代谢产物,并以此分析M-WPI对发酵乳产生的影响。结果表明:在脱脂乳中加入M-WPI,可以提高保加利亚乳杆菌存活率,增加发酵乳的风味及抗氧化活性。采用主成分分析(PCA)和偏最小二乘判别分析(PLS-DA)共确定77种显著差异代谢物,涉及的主要代谢通路为19条。加入M-WPI后葡萄糖、半乳糖等,代谢物上调,提高了保加利亚乳杆菌存活率;癸酸、苹果酸等有机酸上调,能提高发酵乳的口感及改善发酵乳风味。保加利亚乳杆菌发酵乳中上调的代谢物以氨基酸类较多,其中丙氨酸、天冬氨酸和泛酸等参与β-丙氨酸代谢,与发酵乳抗氧化活性提高有关。本研究为加入M-WPI发酵乳营养评价以及相关加工技术和产品开发提供参考。

运用文献资料法、录像观察法和数理统计法,对第51届利物浦体操世锦赛男子全能成绩进行分析,探索优秀全能运动员竞技实力特点,找出我国运动员与国外优秀运动员存在的优势与不足,为全面提升我国男子个人全能运动员竞技实力提供参考。结果显示:我国在全能项目面临前后夹击的局面,形势不容乐观;国外一些全能新秀成长迅速,将来对我国全能夺冠也会造成一定的挑战;男子全能六个单项第一分别被五位运动员所获得,不同选手优势项目不同,没有人能够占据绝对统治地位;对运动员完成情况与最后名次进行斯皮尔曼等级系数分析,发现两者呈非常显著性相关(r=-0.905,P=0.002<0.01),表明完成质量在很大程度上决定着运动员的最终排名,然而竞技体操成绩是由难度与质量共同决定,只有实现“双高”才是取胜的根本保证。
