Maternal and fetal indicators of oxidative stress in various obstetric complications

The present study demonstrates the incidence of increased lipid peroxidation and protein oxidation in both maternal and fetal erythrocytes as markers of oxygen radical activity in different complications of pregnancy. In fetuses born after premature rupture of membranes, lipid peroxidation was significantly elevated as indicated by increased malondialdehyde levels (p<0.05) as compared to controls. Proteolytic activity in the erythrocytes of mothers in this group was also significantly high (p<0.01). In patients delivered by lower segment cesarian section, lipid peroxidation and proteolytic activity in maternal erythrocytes were significantly high (p<0.05 and p<0.001 respectively). In patients with prolonged second stage of labour, lipid peroxidation and proteolytic activity in maternal erythrocytes was significantly higher than in controls (p<0.001 and p<0.05 respectively). In this group, endogenous protein damage due to oxidative stress was significantly high both in the mother and the fetus (p<0.001 and p<0.05 respectively).     

区域信息化与劳动生产率相关关系的实证分析

本文首先定义了衡量区域信息化发展水平的信息化发展指数与衡量区域劳动生产率指标的比较劳动生产率。随后,采用最新的统计数据对二者进行相关分析,发现中国各区域的劳动生产率与信息化发展呈现出极强的区域不平衡性,且信息化发展的区域不平衡性更强,而同区域的信息化发展指数与比较劳动生产率则呈现出较强的相关性,其中第三产业最为明显。最后采用葛兰杰因果关系检验方法进一步确定,在信息化与劳动生产率的互动关系中,信息化为“因”,劳动生产率为“果”。     

Earnings among young and mature Danish university graduates

This paper studies the association between graduation age and earnings among university graduates in Denmark, which is a country with one of the oldest student populations in the world. Exploiting a rich data-set from administrative registers, the current study is able to track labour market career for a longer period of time and to control for more labour market-relevant variables than any previous study of graduation age and earnings. The results show that graduation age has either a slightly positive or an insignificant impact on starting wages within the public sector or a negative impact on starting wages among private sector employees. This applies to both genders, but the differences are stronger among male employees. The analyses of long-term wages reveal a more homogeneous pattern. Mature graduates earn less in all the years investigated. The wage differences are greatest among male graduates employed in private enterprises, and the gap increases throughout their careers.     

李大钊与马克思主义中国化的肇始

李大钊对马克思主义中国化的肇始有着不可磨灭的卓越贡献。他不但是中国最早系统研究和传播马克思主义的先驱,对马克思主义中国化有着独特的理论贡献,而且最早用马克思主义分析解决中国问题,努力把马克思主义与中国工人运动相结合,最早用马克思主义指导反帝反封建革命,最早建立了马克思主义团体和组织。他对马克思主义在中国的广泛传播和马克思主义中国化的肇始发挥了开创性、奠基性的重要作用。     

我国儿童对电视广告的认知情况及态度分析

我国儿童对电视广告的认知发展是受儿童年龄、所处环境和个性特点影响的,通过系统分析得出了电视广告与儿童之间的相互作用机制。了解儿童对广告的态度和儿童对电视广告的信任程度,并在此基础上分析了电视广告对儿童消费行为、价值观和其他行为的影响机理。同时说明了正面的、优秀的广告对儿童的发展有促进作用,而虚假的、低俗的电视广告会对儿童产生不良的影响。通过分析儿童对电视广告的态度和信任程度也可以看出当代儿童有较强的自主意识和选择意识,对待电视广告并不盲从。     

“大跃进”时期广东省实行“劳卫制”述论

“大跃进”时期,广东省大力开展“劳卫制”,先后经历了全面推行、深入发展、形成高潮、转入低谷四个阶段,取得了较为明显的成效,同时也存在着一些问题。要坚持历史唯物主义对“大跃进”时期广东省的“劳卫制”进行全面客观的评价,认真总结经验教训,为新时期各项社会事业的改革和发展提供借鉴。     

通感修辞与通感隐喻

通感修辞是人类感官互通现象的语言表现形式。从传统修辞学、神经生理学、认知语言学三个层面解释这一语言现象,并抽象出通感的认知要素和认知模式。     

我国离婚救济制度若干问题分析

1980年《婚姻法》明确规定了离婚时经济帮助这一救济措施,2001年修订的婚姻法增设了家务劳动补偿与损害赔偿两项救济制度。这三项制度内容抽象,范围过窄,在维护合法权益,保护弱势方、无过错方及受害方利益,彰显公平的价值等方面明显存在不足。其完善:增加损害赔偿的范围,确定经济帮助的标准和适用范围,增加家务补偿的具体内容,扩大权利人的救济范围。     

All that glitters is not gold—Mixed early labour market outcomes of STEM graduates in Poland

The expansion of higher education resulted in a growing interest in post-graduation labour market outcomes. Two conflicting narratives are present in the debate. The first focuses on the shortage of skills and the need for further expansion of the sector and seems to pertain mostly to science, technology, engineering, and mathematics (STEM). The second revolves around over-education and mismatch leading to graduate unemployment or underemployment. Such concerns pertain especially to humanities and social sciences. However, in this article, we argue that the STEM versus non-STEM opposition on which this debate is premised is not adequate for analysing post-graduation labour market outcomes. We leverage a unique administrative dataset comprising monthly records on the labour market status of the entire population of recent Polish university graduates (N = 161,323) to demonstrate the heterogeneity of the STEM category in terms of labour market outcomes and the limited predictive value of the field of study for those outcomes. We argue that the category is too broad and internally diverse to be used as an overarching category, especially in research meant to inform policymaking.
