具有出生率密度制约的非自治SIRS模型

研究了一类具有出生率密度制约的非自治SIRS模型,获得了疾病持续和绝灭的阈值R*和R*,证明了当R*>1的时候疾病将持续存在;当R*<1的时候疾病将会消亡,最后利用Lyapunov泛函方法得到系统全局吸引的一些条件.     

从生育和丧葬仪式看布依族竹图腾崇拜

大量史料记载夜郎王为竹所生和布依族以竹为姓的典故。布依族的民间故事、民歌、神话传说都记录了布依族祖先为竹所生及竹生人的说法。布依族将竹作为其所崇拜的图腾,竹的功能得以神化。生和死是人生最重要的两个仪式,布依族在生育仪式中的“搭花桥”、“改都雅”和丧葬仪式中的“龙戈”、“古庄”、“豪洛”都体现了其对竹的图腾崇拜。布依族人民企图以祭祀等图腾仪式来达到对自然的支配和控制,通过大量的祭祀与巫术活动祈求得到图腾的保护。     

主流经济学理论对企业产生问题的解释及其缺陷

出生体重与3～6岁幼儿身体形态特征相关研究

运用比较分析法,对出生体重与3~6岁幼儿身体形态特征相关研究。结果表明:出生体重与3~6岁幼儿身体形态特征存在一定的关联度,不同出生体重幼儿身体形态特征的差异,主要体现在重与轻两组幼儿。出生体重重的幼儿身体形态发育处于领先,出生体重轻的幼儿身体形态发育低于其他幼儿;不同出生体重幼儿身体形态指标,随着年龄增长而增长,但增长速度不同,体重增长速度最快,其次是身高、坐高、克托莱指数、胸围,增长速度最慢。     

Healthy Birth Practice #1: Let Labor Begin on Its Own

As cesarean rates have climbed to almost one-third of all births in the United States, current research and professional organizations have identified letting labor begin on its own as one of the most important strategies for reducing the primary cesarean rate. At least equally important, letting labor begin on its own supports normal physiology, prevents iatrogenic prematurity, and prevents the cascade of interventions caused by labor induction. This article is an updated evidence-based review of the “Lamaze International Care Practices That Promote Normal Birth, Care Practice #1: Let Labor Begin on Its Own,” published in The Journal of Perinatal Education, 16(3), 2007.     

Imagining accidental fetal citizens: pregnant Mainland women and the cultural politics of birthright citizenship

This essay looks at the mobility of pregnant Mainland women in Hong Kong to expose the reverberations of the SAR government's immigration policies relating to cross-border birth tourism. Pregnant Mainland women and their children (fetuses), as emergent social subjects, embody conflict and the negotiation between population governance and economic benefits. The government denies pregnant Mainland women the right to give birth in Hong Kong based on their non-eligible status while admitting their children to be born in Hong Kong on the grounds that their children meet Hong Kong's future demand for population renewal, in this way boosting the development of childbirth tourism. However, the localism, which has had an extensive influence on Hong Kong local society in recent years, has rejected the SAR government's “population renewal” imaginary by suggesting its own “locust imaginary.” The government's acceptance and the local's exclusion of the population flow between China and Hong Kong imply distinct cross-border subject imaginations. Only by contextualizing and critically analyzing the various othering identities such as the non-eligible or locusts can we better understand the cultural politics of Hong Kong birthright citizenship over recent years.
