职业院校涉外会计专业工作过程导向课程设置探讨

＂工作过程导向＂课程是以一个职业的典型工作任务为基础、以工作过程为导向、以项目教学为典型表现形式的任务引领式的学习领域课程。这种从德国引进的职业教育理念比较符合一般职业学校学生的人才成长规律。在此理论的指导下,通过对涉外会计职业岗位群工作过程的分析,归纳出出纳员、会计员和会计主管等岗位的典型工作任务及相应的学习领域,并举例进行了具体的学习情境设计,初步建立起一套职业院校涉外会计专业的课程体系。

论国家助学贷款补贴政策的生成基础

助学贷款是一种具有公益性的金融产品,市场并不能对其起到充分的调节作用,其突出表现是助学贷款的“贷款难”和“回收难”问题。在这种情况下,公共财政对助学贷款进行补贴,不但可以推动助学贷款发展,而且可以优化教育资源配置,促进收入再分配和宏观经济发展。因此,公共财政对助学贷款进行补贴,既是助学贷款发展的现实需求所致,也是公共财政履行自身职能的必然要求。     

Proteomic analysis of human umbilical vein endothelial cells exposed to PM<Subscript>2.5</Subscript>

Exposure to fine ambient particulate matter (PM_2.5) is known to be associated with cardiovascular disease. To uncover the molecular mechanisms involved in cardiovascular toxicity of PM_2.5, we investigated alterations in the protein profile of human umbilical vein endothelial cells (HUVECs) treated with PM_2.5 using two-dimensional electrophoresis in conjunction with mass spectrometry (MS). A total of 31 protein spots were selected as differentially expressed proteins and identified by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) MS. The results demonstrated that DNA damage and cell apoptosis are important factors contributing to PM_2.5-mediated toxicity in HUVECs. It is further proposed that PM_2.5 can inhibit superoxide dismutase (SOD) activity and increase reactive oxygen species (ROS) and malonaldehyde (MDA) production in a concentration-dependent manner. Induction of apoptosis and DNA damage through oxidative stress pathways may be one of the key toxicological events occurring in HUVECs under PM_2.5 stress. These results indicated that the toxic mechanisms of PM_2.5 on cardiovascular disease are related to endothelial dysfunction.     

幼儿园教师公正:一道艰难的必选题

幼儿园教师公正是指教师在保教工作中体现出来的公平正义.教师的保教行为不能没有公正.公正是教育的应有之义,是促进教师发展的内在要求,是促进幼儿成长的重要因素.公正的践行受制于主观教育素养、客观教育资源以及教育氛围等多种因素.公正的实现需要教师个人、行业与园方以及社会共同作出努力.

Cumulative childhood trauma and psychological maladjustment of sexually abused children in Korea: Mediating effects of emotion regulation

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6–13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma.
