《第22条军规》——小人物永远走不出的陷阱

荒诞派小说《第22条军规》成功地塑造了一批在官僚体制下垂死挣扎却不得而终的小人物形象。正是二十二条军规为小人物的人生设下了永远的陷阱,军规本身的冲突性正是荒诞的象征,体现了位于这样的军规统治下的官僚体制的荒谬腐朽以及当时社会的阴暗丑恶。     

共同的存在,异样的书写——阎连科、萨特、加缪小说比较研究

以萨特为代表的无神论存在主义者认为人的存在先于本质,他们假设上帝已死,人的一切言行缺乏一个可以附着的权威标准。人存在着,其本身无善恶的本质可言。人在行动之前完全有选择的自由,任何一种客观存在的条件都不能成为其作出选择的借口,而且人必须为自己作出的选择承担责任。     

我国轮胎出口的“贫困化增长陷阱”研究

我国轮胎产量和出口量位居世界第一,但出口价格低廉,贸易条件不断恶化,极有可能陷入"贫困化增长陷阱"。首先验证了我国轮胎出口已符合"贫困化增长"发生的前提条件。接着构建贸易条件、行业财富和经济福利等变量,实证检验我国轮胎出口"贫困化增长陷阱"的存在性。研究结果表明,我国轮胎出口尚未陷入"贫困化增长陷阱",但已存在贫困化增长趋势。从要素禀赋、全球价值链、比较优势陷阱等视角,分析轮胎出口呈现贫困化增长趋势的原因,最后提出相关建议。     

对当前高校体育教学改革的反思

根据实践经验和对两年来体育教学改革的反思，指出目前高校体育教学改革中出现的误区，阐述当前高校必须把握两条主线，走“教、学”并重的道路，采取确实可行的办法，让学生实现从被动锻炼到主动锻炼的飞跃，充分调动学生的主体能动性。     

论新型工业化道路与我国动态比较优势的建立

“比较优势陷阱”理论是以批判比较优势理论静态性质为自己立论的。而实际上，现代比较优势理论因承认“要素丰裕度”和“要素密集度”的动态变化而使自己具有了动态性质，所以，“比较优势陷阱”理论依然缺乏充分的理论基础和经验证明。产品要素密集度和国家要素禀赋的动态变化通过推动一国产业结构和技术结构的升级使其赢得动态比较优势，所以，长期推行比较优势战略并不会跌入所谓的“比较优势陷阱”．

Developmental effects of child abuse: A review

Most research investigating the effects of physical child abuse on children's development has been based on uncontrolled or poorly controlled studies having small samples, no long-term follow-up, and weak instrumentation. These studies, as well as some which have been more carefully designed, have generally suggested seriously detrimental developmental consequences in physical, intellectual, behavioral, and emotional areas. Some recent controlled follow-up studies challenge such a negative picture of abuse. In particular, a study by Elmer, which is probably the most carefully conducted study yet done, found that the harmful effects of abuse dissipated years after the abusive incident and that socioeconomic status (SES) and related factors may be more important than abuse in determining the course of child development. To improve the quality and clarity of future research on developmental effects of child abuse, this paper discusses, in four major areas, problems which plague the research. Definition: The extent, type, and frequency of abuse should be more carefully defined to allow studies to be compared. The types and amounts of social service interventions should also be specified. Generalization: Research should include more middle and upper SES children, more of the mildly and moderately abused, and more neglected children to allow generalization to the total population of maltreated children. Causality: Since developmental deficits may be the cause as well as the effects of abuse and because outside factors such as SES may lead to both the abuse and the deficits, there is a need for large-scale longitudinal studies which can untangle the cause and effect web of abuse by following children from birth and measuring many factors which might affect development (e.g., SES, birth abnormalities, abuse). Statistical Analysis: Future studies should always use statistical analysis and should obtain larger samples and utilize outcome and classification measures with demonstrated reliability and validity to increase statistical power.
