历史、民族与语言关系之钩沉——为纪念李文实先生诞辰100周年而作

李文实先生的《西陲古地与羌藏文化》在对地名的考证和对民族历史的某些问题的研究上,充分运用了民族语言材料、语言学理论和方法,论述言辞中肯、精确,分析得深中肯綮,具有入木三分之功.李文实先生是一位著名的史学家,他却能把语言学理论与史学研究结合起来,通过对某些民族语言事实的分析来推论某个历史问题和历史地名,为我们揭开了历史谜团,给我们树立了将历史研究与语言学研究相结合的典范.     

Psychologists’ roles in ending homelessness

Homelessness in the U.S. remains a pernicious social problem despite national coordinated efforts to end it. Psychologists are well positioned to address homelessness through direct service, advocacy, research, and policy work. Results of a survey of psychologist members (n?=?197) and student members (n?=?209) of the American Psychological Association highlighted activities they engaged in related to helping people who experience housing instability and showed psychologists are more compassionate toward those who experience homelessness than is the general public. Respondents suggested a number of factors that would encourage their greater involvement with homelessness issues including receiving more focused training, increased funding for services, and simply being asked by someone to help. Given the continued problem of homelessness, psychologists can play an important role in supporting those who are in this situation. Suggestions for increasing training and engagement of psychologists are discussed.

摩托车排放标准的执行困境及修订建议

2007年,我国发布了现行的摩托车排放标准（中国Ⅲ阶段）并开始陆续实施.和原排放标准（中国Ⅱ阶段）比较,现行排放标准的要求更加严格,排放限值大幅度下降,但实施效果并不理想.文章从我国摩托车行业产品特点、销售市场特点、电喷和电控化油器配套企业生产能力、技术能力的研究等方面,分析了摩托车排放标准执行困境产生的原因.并对行业排放标准执行现状、主管部门监督情况等进行了研究,认为排放标准的起草修订工作是解决目前困境的一个良好契机,起草工作应充分考虑行业现状,制定详细的执行方案,标准内容应分步骤、分时段建立相应的目标,逐步提高.     

Discriminating among Weibull,log-normal,and log-logistic distributions

In this article, we consider the problem of the model selection/discrimination among three different positively skewed lifetime distributions. All these three distributions, namely; the Weibull, log-normal, and log-logistic, have been used quite effectively to analyze positively skewed lifetime data. In this article, we have used three different methods to discriminate among these three distributions. We have used the maximized likelihood method to choose the correct model and computed the asymptotic probability of correct selection. We have further obtained the Fisher information matrices of these three different distributions and compare them for complete and censored observations. These measures can be used to discriminate among these three distributions. We have also proposed to use the Kolmogorov–Smirnov distance to choose the correct model. Extensive simulations have been performed to compare the performances of the three different methods. It is observed that each method performs better than the other two for some distributions and for certain range of parameters. Further, the loss of information due to censoring are compared for these three distributions. The analysis of a real dataset has been performed for illustrative purposes.     

汉英诗歌中词汇衔接的对比研究——以《园丁集：英汉对照》节选为例

运用对比分析的方法,以韩礼德和哈桑的词汇衔接理论为基础,从语篇角度分析《园丁集》英文本和汉译本中的词汇衔接关系,发现两种版本都综合运用了词汇的同现和复现关系,构成了衔接紧密、脍炙人口的语篇,但英文本和汉译本的词汇衔接手段并非一一对应使用,汉译的原词复现使用多于原诗,且汉译的词汇衔接手段更丰富,更注重对仗的工整美。     

农村留守青少年信仰基督教的现状及对策

随着基督教在农村地区的迅速传播,农村留守青少年成为基督教传播的对象,信仰人数多、占比高,且呈增长趋势。留守青少年信仰基督教具有受到留守家庭熏陶与默许、同伴相互吸引入教、积极参加聚会活动但并不了解基督教的特点,是社会、家庭、学校教育不足等多种因素交织作用的结果。解决留守青少年的信教问题,需要家庭、学校、政府多方协作,家庭需要给予留守青少年更多的情感关爱和正向引导;学校应该更加重视留守青少年的德育工作,培育学生树立科学的价值观;政府需要打击违法传教活动,为留守青少年建设各类闲暇活动室。
