人力资本理论对继续教育投资倾向的影响

纵观世界发展史,劳动力一直是经济学关注的生产要素,但近半个世纪以来劳动力才作为人力资本来系统地加以研究。人力资本理论从古典经济学中萌芽,经过马克思主义经济学和新古典经济增长理论的理论准备,最终促成舒尔茨从宏观层次研究并建立了人力资本理论。此后,贝克尔等人从中观层次做了大量的实证研究,而现代劳动经济学则更关心微观层次的实证研究,为继续教育的理性投资提供了更加科学的依据。     

汉、回民族4对遗传性状的调查——以河西学院为例

通过对河西学院汉、回民族学生的ABO血型、单双眼睑、耳垂有无及舌卷曲4对遗传性状的调查,比较了这4对性状的基因频率在两民族间的分布.结果表明:ABO血型、单双眼睑及耳垂有无3对遗传性状的基因频率在汉族和回族间存在明显差异,而舌卷曲基因频率在两民族间差异不大.     

对高职公共英语课时减少的思考

一方面公共英语课程在高职教育中有着举足轻重的作用,另一方面却面临其课时减少的尴尬困境。面对这一情况,我们要全面认识公共英语课程的作用和采取应对措施。     

维特根斯坦的人格瑕疵审视

哲学界从不同角度把维特根斯坦的人格瑕疵笼统地界定为:傲慢、苛求、粗暴、自私、多疑、悲观,并且以此贬损或撼动其伟大与崇高的哲学地位。从历史和现实的视角观之,维特根斯坦的人格瑕疵不但有其独特的历史背景,而且折射出他冲破哲学藩篱的人品光辉,具有治学严谨、和蔼可亲和乐善好施的美德。     

Arachnoid cell involvement in the mechanism of coagulation-initiated inflammation in the subarachnoid space after subarachnoid hemorrhage

Objective: To assess if arachnoid cells have the capability to present antigen and activate T-lymphocytes after stimulation by bloody cerebrospinal fluid (CSF), and to illuminate the mechanism of coagulation-initiated inflammation in the subarachnoid space after subarachnoid hemorrhage (SAH). Methods: Arachnoid cells were cultured, characterized, and examined by immunofluorescence for the basal expression of human leukocyte antigen-DR (HLA-DR). Expression of HLA-DR, after co-culturing arachnoid cells in vitro with bloody CSF, was investigated by immunofluorescence and flow cytometry (FCM). The variation of arachnoid cells' ultrastructure was observed by transmission electron microscope (TEM). Arachnoid cells were co-cultured with peripheral blood mononuclear cells (PBMCs). The content of soluble interleukin-2 receptor (sIL-2r) in culture medium was detected by enzyme-linked immunosorbent assay (ELISA). Results: (1) Arachnoid cells were successfully cultured for many passages. The immunofluorescent staining was positive for HLA-DR in over 95% of the human arachnoid cells. The punctate HLA-DR was distributed in cytoplasm and not in the karyon. (2) After co-culturing arachnoid cells in vitro with bloody CSF, numerous particles with strong fluorescence appeared in the cytoplasm on Day 6. On Day 8, the quantity of particles and fluorescent intensity were maximal. FCM showed that the percentage of HLA-DR expressing cells was (2.5±0.4)% at the first 5 d, increasing to (60.8±3.6)% on Day 7. (3) After co-culturing arachnoid cells in vitro with bloody CSF, many lysosome and secondary lysosome particles were present in the cytoplasm. Hyperplasia of rough endoplasmic reticulum and enlarged cysts were observed, with numerous phagocytizing vesicles also observed at the edge of the arachnoid cells. (4) Arachnoid cells stimulated by bloody CSF were co-cultured in vitro with PBMCs. The content of sIL-2r in the culture medium, having been maintained at around 1.30 ng/ml during the first 3 d, had increased by Day 4. The content of sIL-2r peaked 7.53 ng/ml on Day 7 and then reduced gradually. Conclusions: (1) Basic HLA-DR expression is present in arachnoid cells. (2) After stimulation by bloody CSF, arachnoid cells have the potential to serve as antigen presenting cells (APCs) and the ability to activate T-lymphocytes, indicating that arachnoid cells are involved in the mechanism of coagulation-initiated inflammation in the subarachnoid space after SAH.     

药品专利与人权的冲突与调适

近年来,随着全球化的推进、商品和人口的自由流动,各种传染性疾病快速蔓延于全球,人类对药品的需求也随之变得迫切。而由于对药品实施专利权的保护,导致药品价格居高不下,很多人由于经济原因而无力购买治疗疾病所需的基本药品,这与国际社会所大力提倡的人权保护显得格格不入。作为私权的药品专利权和作为人权的生命健康权之间存在着冲突与矛盾。在协调二者的关系上,药品专利制度本身的完善和新药品的研发是关键。     

对远程开放教育人力资源管理课程教学的思考与探索

远程开放教育人力资源管理课程的教学,应以培养学生自主学习的能力,掌握最基础的管理理论与实务,创造性的开展管理工作为核心。为经济建设培养既具备理论知识,又能学以致用的适用性人才,是远程开放教育人力资源管理教学的最终目标。     

《狂人日记》“吃人”意象的主题与实质

《狂人日记》中“吃人”意象是探析人物内心活动过程的一个观照点。本文通过作品精心创设的“传统,反传统”、“理性/非理性”、“看／被看”、“吃,被吃”的对立语境,探察“吃人”意象在文本“破”与“立”相互转换过程揭示作品主题的意义,以期为阅读及理解作品提供一些思路。     

指称人的动物隐喻的认知机制研究

被淡忘的节日——人日

农历正月初七为“人日”,亦称“人胜节”。人日即人的生日。这在我国至少有两千多年的历史。人日在汉代有占卜吉凶等风俗,魏晋时又有登高习俗。由于人日有戴华胜祈福避灾的习俗,于是唐人将华胜称作“人胜”。而人日兼立春,唐人习俗剪双彩送亲友,更是别有一番情意。人日节当家的节日食品是“七菜羹”,它和除夕吃年夜饭、元宵节吃汤圆等一样,都是民间传统习俗。唐代是人日的鼎盛时代;明清时代以降,由于集权政治日益恶化,人日节逐渐淡出视野。
