长江三角洲南部下蜀黄土与硬粘土层关系初探

从气候变化和地形影响两个角度 ,对长江三角洲南部晚更新世地层中西部丘陵区的下蜀黄土与东部平原区的硬粘土层进行了初步探讨 ,认为二者的物质来源都是末次冰期盛冰期由风力搬运堆积而形成的。     

试论文化作为广告传播的软媒介

在产品同质化和媒介数量剧增、信息爆炸的社会条件下,作为大众传播形式之一的广告传播仍然采用传统的硬媒介,难以取得理想的传播效果。因此,充分研究广告受众,寻找适宜的创意和表现形式成了当务之急,文化是传受双方共享的信息资源。     

艰苦奋斗精神的时代内涵及弘扬途径

艰苦奋斗精神是中华民族的传统美德和民族精神 ,中国共产党的三代领导人都高度重视用艰苦奋斗精神教育和武装全党。实现中华民族伟大复兴 ,唱响时代主旋律 ,提高全民族的思想道德素质和科学文化教育水平 ,都需要弘扬艰苦奋斗精神。应当与时俱进 ,科学地理解艰苦奋斗精神的时代内涵 :艰苦奋斗是志存高远、克己奉公的人生境界 ,是昂扬向上、发奋图强的精神风貌 ,是坚韧不拔、求真务实的工作作风 ,是简约朴素、吃苦耐劳的生活态度。培养大学生艰苦奋斗精神的有效教育方式 ,可以有以下几种 :开展励志教育 ;融入专业教学 ;大力加强实践教学 ;大力加强体育工作。     

试析利他行为的不同类型及其原因

利他行为可区分为软利他行为和硬利他行为.软利他行为可以用人的利己心解释,而硬利他行为则否.硬利他行为又可以分为有限硬利他行为和无限硬利他行为,有限硬利他行为服从边际效用递减率,而无限硬利他行为则否.无限硬利他行为的形成与进化无法单纯用个体之间的竞争来解释,它是人类在个体之间和群体之间多个层次的竞争当中的适应性行为,是在多层竞争中形成与进化的,是多层竞争选择的结果.     

Labor Market Disparities Between African Americans and Afro Caribbeans: Reexamining the Role of Immigrant Selectivity

Black immigrants from the Caribbean have long attained greater labor market success than African Americans. The most recent studies show that Afro Caribbeans have earnings that are approximately 16% greater than African Americans and that Afro Caribbeans are as much as 21% more likely to be employed than African Americans. The most prominent explanation for greater Afro Caribbean success is that, because they have chosen to migrate, Afro Caribbeans are positively self‐selected on characteristics that are key for success in the U.S. labor market. Proponents of immigrant selectivity argue that migrants have greater levels of both hard and soft skills than nonmigrants. Using data from the National Survey of American Life—the first social survey to provide a nationally representative sample of both African Americans and Afro Caribbeans—this study finds that Afro Caribbeans have greater hard skills than African Americans but split the difference on two measures of soft skills: African Americans and Afro Caribbeans are matched on John Henryism, but African Americans have greater personal mastery than Afro Caribbeans. Contrary to expectations, controlling for differences in hard and soft skills does not provide for a meaningful reduction in labor market disparities between African Americans and Afro Caribbeans.     

一生多半在车船--李笠翁“苦游”四海

李笠翁一生不断搬家和出游，自谓“一生多半在车船”，当是实录。单说长游，就有五次：最早的一次是康熙三四年间游粤；紧接着是康熙五至七年游京师连着游晋秦；回金陵住了一年多后，于康熙九年游闽；又隔一年，游楚；最后是康熙十二至十三年第二次游京师。此外，笠翁还在68岁高龄时，于贫病交加之中作了一次湖州之游。在别人，外出大都是“乐”游；而在笠翁，则是“苦”游。在别人，是衣食无忧，到外面长见识，增阅历，或观赏大自然的美景；而在笠翁，则是去“就食”，即像牧民“逐水草而居”找饭吃。别人是“吃饱了饭”去游玩“消食”；而笠翁却是“饿着肚子”出游“找食”，自谓“为饥驱而走四方”。当然，“苦”中有乐，“饥驱四方，遍历名胜”；同时也有收获———除“化缘”得“食”之外，还收获了诗文，也收获了友谊。但是，笠翁出游，“苦”是主打，“乐”是陪衬；“苦”是正业，“乐”是副产品。     

Forensic Evaluation of Deaf Individuals: Challenges and Strategies

ABSTRACT

Forensic evaluation of deaf individuals presents unique challenges due to many examinees’ fund of information deficits, potential for language deprivation, and examiners’ frequent lack of creativity regarding communication methods. This article describes challenges most frequently encountered in competency to stand trial and criminal responsibility evaluations and offers strategies for overcoming them. The value of employing multiple communication methods, especially the use of illustrations, is emphasized. Suggestions also are offered regarding preparing evaluation reports and effectively communicating “key deaf fundamentals” to legal personnel. Encouragement is offered for qualified, sign-fluent professionals to engage in forensic work.

Practical Maximum Pseudolikelihood for Spatial Point Patterns(with Discussion)

This paper describes a technique for computing approximate maximum pseudolikelihood estimates of the parameters of a spatial point process. The method is an extension of Berman & Turner's (1992) device for maximizing the likelihoods of inhomogeneous spatial Poisson processes. For a very wide class of spatial point process models the likelihood is intractable, while the pseudolikelihood is known explicitly, except for the computation of an integral over the sampling region. Approximation of this integral by a finite sum in a special way yields an approximate pseudolikelihood which is formally equivalent to the (weighted) likelihood of a loglinear model with Poisson responses. This can be maximized using standard statistical software for generalized linear or additive models, provided the conditional intensity of the process takes an 'exponential family' form. Using this approach a wide variety of spatial point process models of Gibbs type can be fitted rapidly, incorporating spatial trends, interaction between points, dependence on spatial covariates, and mark information.
