重新评价马克·吐温的代表作——《汤姆·索耶历险记》和《哈克贝里·费恩历险记》(英文)

马克·吐温,这位在美国文学史上开一代创作先河的小说家,为后人留下了20多篇不朽佳作.其中,令人惊讶的是:在他全部作品中,两部描写少年历险故事的著作——《汤姆·索耶历险记》和《哈克贝里·费恩历险记》,始终处于最突出的位置,并一直被中外学者公推为其代表作.于是我们不得不深思这样一个问题,作为美国文坛杰出代表人物之一的马克·吐温为什么选择了儿童的角色,而又把他们塑造很空前成功?纵观文学界对马克·吐温作品及其人物形象的有关研究成果和论述,似乎都不能够圆满地答复这个问题.     

Government Risk Management Priorities: A Comparison of the Preferences of Asian Indian Americans and Other Americans

A survey was conducted of approximately 200 Asian Indian Americans and 200 other residents of New Jersey in order to understand the risk management priorities that they want government to have. We found that Asian Indian Americans, especially younger women, focused on personal/family risks, such as alcohol and drug abuse, sexual abuse, and domestic violence. The New Jersey comparison group, in contrast, placed war/terrorism and loss of health care services and insurance at the top of their priorities for government. These results suggest stressful acculturation-related issues within the Asian Indian community. Both populations want more risk management from government than they believe government is currently providing. Respondents who wanted more from government tended to dread the risk, be fearful of the consequences, trust government, and have a feeling of personal efficacy. Within the Asian Indian American sample, wide variations were observed by language spoken at home and religious affiliation. Notably, Muslims and Hindi language speakers tended not to trust government and hence wanted less government involvement. This study supports our call for studies of recent migrant populations and Johnson's for testing ethnic identity and acculturation as factors in risk judgments.     

A regression-based smoothing spline Monte Carlo algorithm for pricing American options in discrete time

American options in discrete time can be priced by solving optimal stopping problems. This can be done by computing so-called continuation values, which we represent as regression functions defined recursively by using the continuation values of the next time step. We use Monte Carlo to generate data, and then we apply smoothing spline regression estimates to estimate the continuation values from these data. All parameters of the estimate are chosen data dependent. We present results concerning consistency and the estimates’ rate of convergence.     

从尤瑟夫·海勒的“黑色幽默”文学透析美国社会

海勒的《第二十二条军规》运用讽刺暴露等手法，无情地揭露和鞭挞了战争的荒谬和不道德以及美国社会的黑暗和罪恶。     

从美国进步主义运动的领导主体看运动的特性

学术界在认识美国进步主义运动的性质方面迄今尚有分歧，存在着“旧中产阶级争夺权势说”、“企业主利益冲突说”、“城市新中产阶级价值观改造说”和“中产阶级文化重建说”等多种观点。然而对这一运动的中坚力量与领导成分的考察则表明，知识分子在运动的领导主体中，占据了相当大的比例，并发挥了先锋骨干作用。从这一角度来看，美国进步主义运动可以被界定为是一次由知识分子倡导的社会改革运动。     

试析美国高等教育中的学分制及其借鉴意义

学分制是美国高等教育系统中普遍使用的衡量高校学术工作的行之有效的手段。本文对学分制在美国高等教育体制中产生的历史、发展过程及应用的范围进行了分析、探讨, 并给予了客观的评价, 最后指出了它对于中国高等教育学术管理体制的借鉴意义, 并提出了几点个人的建议。     

African American family life in societal context: Crisis and hope

Since 1965 hundreds of articles and books have been published about African American families. Nevertheless, our understanding of these families continues to be limited. There is a tendency to gloss over important within-group differences; thus, monolithic, stereotypic and inaccurance portrayals of Black family life are common. This paper sets aside debates of Black family pathology or viability, focusing instead on these families' essential character. The paper seeks to understand Black families on their own terms, locating them in relevant social, historical, political and cultural contexts. Key empirical patterns and trends reveal dramatic changes in Black family geographic location, headship, quality of life and socioeconomic status since 1950.A complex picture is revealed. There has been gradual but steady overall improvement alongside persistent, extreme racial disparties and pronounced class disparities among Black families. The proposed Black Family Socio-Ecological Context model specifies and connects institutional, interpersonal, environmental, temporal and cultural facts that shape the essential character of Black family life in such a way as to produce characteristics simultaneously shared and idiosyncratic. The model also provides an organized, systematic accounting of research and public policy issues relevant to the study of African American families.An early version co-authored with Richard A. English was presented during the National Council on Family Relations Meetings in Portland, Oregon, October 1980.     

20世纪美国黑人大迁徙与南部三农问题之关系

南北战争后,美国南部长期面临农业生产方式落后、农民贫困、农村社会发展缓慢等三农问题。上述问题与南部的种族问题相互交织,加剧了南部社会的落后与黑暗。这其中,南部黑人受害最为深重,他们被迫大规模迁徙到美国其他地区。20世纪美国有两次黑人大迁徙的高潮,到20世纪70年代有600多万南部黑人迁徙。美国南部的三农问题是黑人大迁徙的经济原因,但黑人大迁徙又反过来推动了三农问题的解决,由此可见迁徙自由对于解决三农问题的重要意义。     

高校学生干部角色意识嬗变实证研究

高校学生干部的角色意识特点直接影响其行为方式及群体作用发挥的积极效果,并深刻影响高校育人质量和教育培养任务.为此,笔者运用自编问卷分别对高校学生进行了两次大型调查,将社会转型期不同年代大学生干部的角色意识着重从追求动机、合格标准、产生方式、角色扮演、价值取向几个维度进行比较分析,结果表明十几年来高校学生干部的角色意识发生了明显变化.基于学生干部角色意识的新特点,提出了“加强学生干部分类指导”等等培养大学生干部角色意识的四方面建议.
