Parental leave policies and parents' employment and leave‐taking

We describe trends in maternal employment and leave‐taking after birth of a newborn and analyze the extent to which these behaviors are influenced by parental leave policies. Data are from the June Current Population Survey (CPS) Fertility Supplements, merged with other months of the CPS, and cover the period 1987 to 1994. This time span is one during which parental leave legislation expanded at both the state and federal level. We also provide the first comprehensive examination of employment and leave‐taking by fathers of infants. Our main finding is that leave expansions are associated with increased leave‐taking by both mothers and fathers. The magnitudes of the changes are small in absolute terms but large relative to the baseline for men and much greater for college‐educated or married mothers than for their less‐educated or single counterparts. © 2009 by the Association for Public Policy Analysis and Management

马克思劳动权利思想的内涵及其启示——基于《资本论》的文本分析

作为马克思主义政治哲学的核心范畴,权利在《资本论》中被核心表征为了劳动权利。马克思通过对劳动所有权的权能分离、劳动权利与资本权力的冲突展开对劳动权利的阐释,完成了对劳动权利的核心内涵的事实判断。也正是基于这一指认,马克思在《资本论》中以劳动权利的未来图景为启示,搭建了以保障劳动权利的劳工权益为手段,以劳动权利的价值评价为目的的框架,以期使劳动权利获得自由的价值从而实现人的自由全面发展。     

艾灸对腹泻型肠易激综合征模型大鼠海马与结肠组织中IKKβ/IKBα/NF-κB通路的影响

目的观察艾灸对腹泻型肠易激综合征(diarrhea predominant irritable bowel syndrome,IBS-D)模型大鼠海马与结肠组织中核因子κB抑制蛋白(inhibitor of nuclear factor kappa B,IκB)激酶β(IκB kinase beta,IKKβ)、核因子κB抑制蛋白α(NF-kappa-B inhibitor alpha,IKBα)、核因子κB(nuclear factor kappa B,NF-κB)(P65)相对表达水平的影响,探讨艾灸治疗IBS-D的机制。方法将24只健康雄性SD大鼠随机分为空白组、模型组和艾灸组,每组8只。采用慢性束缚联合番泻叶灌胃方法建立IBS-D大鼠模型。艾灸组予以艾灸"天枢""上巨虚",每日30min,每日1次,共治疗7d。治疗后,观察大鼠稀便率和直肠扩张所引起腹部回缩反射(abdominal withdrawal reflex,AWR)的最小容量阈值;蛋白质印迹法检测海马和结肠组织中IKKβ、IKBα、NF-κB(P65)蛋白表达水平。结果与空白组比较,模型组AWR的最小容量阈值明显下降(P<0.05),稀便率明显升高(P<0.05);海马和结肠组织中IKKβ、IKBα、NF-κB(P65)蛋白表达水平明显增加(P<0.05)。与模型组比较,艾灸组AWR的最小容量阈值明显升高(P<0.05),稀便率明显下降(P<0.05);海马和结肠组织中IKKβ、IKBα、NF-κB(P65)蛋白表达水平显著降低(P<0.05)。结论艾灸"天枢""上巨虚"改善IBS-D大鼠腹泻症状和内脏高敏感性可能与艾灸抑制海马与结肠组织IKKβ/IKBα/NF-κB信号通路有关,且其作用机制可能是通过脑-肠轴途径实现的。     

论道德建设的三个实践维度

现代社会道德文化的创造和延续,需要必要的资源,而资源的最重要的一个方面是来自于社会道德生活世界的实践创造和经验积累。鉴于此,道德建设的实践归宿是回归日常生活,道德建设的实践方式应重视道德践履,道德建设的实践保障要依靠制度支撑。     

吸食注射毒品行为非犯罪化探析

2006年3月1日起施行的《中华人民共和国治安管理处罚》第七十二条第三款将吸食、注射毒品的行为以法律的形式确定为违法行为予以治安行政处罚。站在坚持吸食、注射毒品非犯罪化的立场,对该类行为从犯罪学的角度进行综合考察、借鉴恢复性司法理念,对吸食、注射毒品者在采取非刑罚处罚的基础上,如何施以人性关怀、力求为减少和控制吸食、注射毒品行为略陈管见。
