Prenatal depression, violence, substance use, and perception of support in pregnant middle-class women          下载免费PDF全文

Anderson C  Roux G  Pruitt A 《The Journal of perinatal education》2002,11(1):14-21

The purpose of this study was to explore the vulnerability for postpartum depression among financially, educationally, and socially advantaged middle-class women (n = 31). Twenty-nine percent reported prenatal depression, 13% reported intimate partner violence, and 22% reported concerns with partner relationships and support expectations after delivery. No illegal substances were reported; however, a past history of smoking and excessive use of caffeine was disclosed. Implications for practice focus on the need to screen and implement intervention programs for these social problems and to adopt measures as a universal standard of care for all women, regardless of demographic advantages.  相似文献   

试析邓小平对社会主义民主理论的发展   总被引：3，自引：0，他引：3  

封大中 《天津师范大学学报(社会科学版)》2003,23(3):6-11

社会主义民主理论是马克思主义的重要组成部分。邓小平不仅继承了马克思主义创始人提出的实现人民当家做主的思想，而立在民主与社会主义等问题上有诸多创新。只要我们坚持党的领导，不断丰富邓小平的社会主义民主理论，实行依法治国，就一定能建立起高度的社会主义民主政治。  相似文献

Secondary immunization inhibits drug induced apoptosis<Emphasis Type="Italic">in vivo</Emphasis>     

Winston Costa Pereira  Muddanna S. Rao  D. M. Vasudevan 《Indian journal of clinical biochemistry : IJCB》2003,18(2):161-168

Immunization with a proper dose of an antigenic stimulus leads to cell proliferation and antibody response of circulating lymphocytes. We have previously observed that Secondary immunized spleenocytes resist ceramide-mediated apoptosisin vitro. Our present study is aimed at investigating thein vivo effect of immunization on apoptosis. Mice were subjected to either Primary or Secondary dose with Tetanus Toxoid. Unimmunized spleenocytes served as controls. Unimmunized, Primary and Secondary immunized mice were later exposed to chemotherapeutic drugs such as Etoposide/Methotrexate/Vincristine to induce apoptosis. Apoptosis was studied by using the Feulgen reaction on 5μ thin parafin sections of spleen. It was observed that Secondary immunized mice showed a lower percentage of apoptosis as compared to Primary or Unimmunized mice that was subjected to either of the chemotherapeutic drugs. It was thus concluded that Secondary immunization inhibits the process of chemotherapeutic drug induced apoptosis in vivo.  相似文献   

Maintenance of responding when reinforcement becomes delayed     

Costa DS  Boakes RA 《Learning & behavior》2007,35(2):95-105

In four experiments with rats, we examined the persistence of behavior when reinforcement was switched from immediate to delayed. In Experiment 1, lever pressing elicited by instrumental training with immediate reinforcement continued when a 20-sec delay of reinforcement was introduced (easy-to-hard condition), whereas when the delay condition was introduced from the start (hard-to-hard condition), responding remained low throughout. A similar result was obtained in Experiment 2, in which lever pressing was elicited by a classical conditioning (autoshaping) procedure. In Experiment 3, rats initially trained with delayed reinforcement continued to respond at a low rate when switched to immediate reinforcement (hard-to-easy condition). By measuring magazine entry (goal tracking) as well as lever pressing (sign tracking) in Experiment 4, we confirmed that such transfer effects at least partly involve the persistence of whatever type of behavior was initially dominant.  相似文献   

论胡中藻案及对江西的影响     

阳达 《江西教育学院学报》2011,32(6):138-141

胡中藻案是乾隆借文字狱的形式打击朋党的一宗大案。乾隆整治的对象实是分别以鄂尔泰、张廷玉为首的两大党派,而试图通过胡中藻案杀一儆百,以进一步加强君权统治。乾隆及查案大臣刻意误读胡中藻诗句含义,并且严查胡中藻的结党行为,掀起了一场政治运动,对江西的社会风气都产生了很大的影响。  相似文献

张延迟  顾羽洁  解大  张明  李景兴 《实验室研究与探索》2011,30(3)

设计并实现了一个小型风力发电机的外特性测试平台,平台包括低速开放式风洞、数据采集系统两部分.风洞设计成口径3.5 m的直流式风洞,实验段采用圆形截面,动力段采用多风机提供动力,在风流通过蜂窝器后,大大改善了风流效果并提高了可靠性.数据采集系统通过工业控制数据采集卡对风速、风力发电机转速、输出电压、电流等进行数据采集和处理.通过对某小型风力发电机进行测试的结果表明,平台可满足测试小型风机外特性的实验要求.  相似文献   

微电网的仿真与实验系统Ⅱ—建模仿真及实现     

解大  顾羽洁  徐涛  艾芊  张明  金之检 《实验室研究与探索》2011,30(10):53-58,145

文中基于美国西部联合电网(Western Systems Coordinating Council,WSCC)3机9节点系统,建立了1个带有逆变并网接口的输电网模型,并利用逆变并网接口模型模拟了微电网与上级输电网的连接,对微电网对上级电网电压与频率的支持情况进行了数字仿真。仿真结果表明在上级输电网的有功与无功负荷发生突变时,微电网的接入使上级输电系统的有功与无功功率能够实现就地平衡,并保持系统频率与电压幅值的稳定。整个微电网系统仿真环境设定均按照实验室所能达到的低电压低容量条件下完成。文中所有仿真算法及结果均在PSCAD/EMTDC软件环境及动态模拟实验室中得到验证。  相似文献
