史料引用致误原因分析

史料是史学研究的基础.但自古以来,由于种种原因,错误的或者事实模糊不清的史料很多,如果不作必要的考证鉴别,很难获得科学的研究成果.造成史料引用致误的原因是多方面的,归结起来主要有:(1)史料本身无误,由于没有正确理解原意或者标点不正确而致误;(2)史料本身无误,由于引用者推断不确而致误;(3)史料内容比较含蓄,由于引用者缺乏深入辨析而致误;(4)没有直接引用原书而致误;(5)因版本不善而造成史料的错误或脱漏;(6)史料本身就有错误.     

"城中村"城市化的对策研究

从《诗经》情歌看先民的宗教情结

情歌在<诗经>中占有非常重要的地位,其情节形象地再现了古代社会隆重的祭高禖仪式,这一仪式与先民的生殖崇拜密切相关,不仅反映了人们自由、奔放的性爱意识,揭示了人们对生命的热爱和重视,而且寄托着远古民族浓重的宗教情结,从而使<诗经>具有了深厚的人类学价值和深远的文化意蕴.     

试论晚年白居易的自足、闲适思想

源于老庄思想的自足、闲适心态 ,是晚年白居易之所以能在洛阳实现身心自然合一的“中隐”生活的心理基础。因为自足 ,才会身心闲适 ,适又以闲为前提条件。其闲适诗中失落了表现社会责任的儒家精神。     

兰州城关区回族居住格局研究

本文运用都市人类学的研究方法,对兰州市城关区回族的居住格局进行了研究。研究表明,随着民族迁移、社会发展、城市化进程的加快,聚居区转变为杂居区,以及城区边缘地带出现的新聚居区,这种变化还在进行之中。这种居住格局的变化虽然促进了民族团结、社会安定与发展,但是也出现了一些新问题。为此,本文对未来回族的居住格局进行了初步设想。     

The functional patterns of adolescent mothers leaving foster care: Results from a cluster analysis

Few studies have explored the outcomes of adolescent mothers leaving foster care, especially using person‐oriented methods. The current study employed a cluster analysis to identify unique patterns of functioning among adolescent mothers aged 19 (n = 777). Data from the National Youth in Transition Database and the Adoption and Foster Care Analysis and Reporting System were utilized. Findings revealed five subpopulations characterized by distinct constellations of outcomes at age 19. The largest group (43%) exhibited competent functioning across all the domains studied—its members were connected to school and/or employment and did not experience homelessness, substance abuse referrals, or incarceration during the past 2 years (i.e., “resilient”). A relatively small group (12%) exhibited challenges across all the above‐referenced domains, whereas the remaining groups presented challenges in some domains, but not in others. Follow‐up analyses revealed that adolescent mothers classified as resilient at age 19 had the lowest rates of congregate care placements and the highest rates of nonrelative foster care placements at age 17. Moreover, they had lower placement instability and higher rates of extended foster care as compared with members of the other clusters. Implications for practice, policy, and research are discussed.     

从《父子之间》看早期生活对奈保尔文学创作的影响

《父子之间:家庭书信集》为我们研究奈保尔提供了最为真实可信的历史材料。通过分析这部家庭书信集,揭示出作家少年时代特立尼达生活的"文化悬挂",青年时代留学英伦经历的"文化祛根",以及父亲在文学上对儿子的影响;所有这些对于奈保尔精神气质和文学理念的初步形成,有着不可低估的作用。更重要的是,作家后来的"文化无根"状态,与这一时期的生活有密切关系。对这部书信集的研究,是全面了解奈保尔的必要起点。     

林语堂人文思想的几个特征

林语堂的人思想具有如下特征：以人和人生作为出发点和归宿,以真实的人生、人生实践和人生感悟作为立论的基础;总是用智慧去观照世界,区分美丑,确认价值,即以智慧为根本;古今中外,兼容并包,在各种化体系中任意驰骋,在所谓“矛盾”、“对立”中自由出入;常识健全,且因看多了常识失落给人类明带来的灾难后果,而热切呼唤其回归。因此,林语堂很独异,总是远离权威、成见和时尚。     

The Use of Simulation to Reduce the Domain of “Black Swans” with Application to Hurricane Impacts to Power Systems

Recently, the concept of black swans has gained increased attention in the fields of risk assessment and risk management. Different types of black swans have been suggested, distinguishing between unknown unknowns (nothing in the past can convincingly point to its occurrence), unknown knowns (known to some, but not to relevant analysts), or known knowns where the probability of occurrence is judged as negligible. Traditional risk assessments have been questioned, as their standard probabilistic methods may not be capable of predicting or even identifying these rare and extreme events, thus creating a source of possible black swans. In this article, we show how a simulation model can be used to identify previously unknown potentially extreme events that if not identified and treated could occur as black swans. We show that by manipulating a verified and validated model used to predict the impacts of hazards on a system of interest, we can identify hazard conditions not previously experienced that could lead to impacts much larger than any previous level of impact. This makes these potential black swan events known and allows risk managers to more fully consider them. We demonstrate this method using a model developed to evaluate the effect of hurricanes on energy systems in the United States; we identify hurricanes with potentially extreme impacts, storms well beyond what the historic record suggests is possible in terms of impacts.     

弱电解质溶液中c／ka^o比值对解离度误差的影响

介绍了溶液中弱电解质平衡体系的pH计算是《无机化学》课程中的重要基础理论知识。为简化计算经常需要引入近似条件，这样必然造成误差。通过理论计算解释了不同c／ka^o值与解离度误差的关系和不同解离度误差对应的c／ka^o值，对学生正确理解相关内容大有助益，是教材内容的必要补充。
