Racial Differences in Abused Older African American Males, Caucasian Males, and their Abusers

This study examined racial differences between mistreated and abused older African American and Caucasian men. The racial and gender differences of their perpetrators were also examined. Data from a single elder abuse provider agency in the State of Illinois were analyzed. Differences with respect to physical abuse, emotional abuse, physical neglect, deprivation, confinement, and financial exploitation were examined, as were demographic characteristics and limitations of victims and abusers.

Empirical likelihood confidence intervals for the mean of a population containing many zero values

If a population contains many zero values and the sample size is not very large, the traditional normal approximation‐based confidence intervals for the population mean may have poor coverage probabilities. This problem is substantially reduced by constructing parametric likelihood ratio intervals when an appropriate mixture model can be found. In the context of survey sampling, however, there is a general preference for making minimal assumptions about the population under study. The authors have therefore investigated the coverage properties of nonparametric empirical likelihood confidence intervals for the population mean. They show that under a variety of hypothetical populations, these intervals often outperformed parametric likelihood intervals by having more balanced coverage rates and larger lower bounds. The authors illustrate their methodology using data from the Canadian Labour Force Survey for the year 2000.     

Unequal at the Starting Line: Creating Participatory Inequalities across Generations and among Groups

We investigate how inequalities in political participation are shaped across generations by considering the influence of family background--in particular, parents' education and political involvement--on political participation. We pursue this issue, first, for individuals, investigating the effects of parental characteristics on the participatory profile of their offspring. Then, we use what we have learned to understand how group differences in political participation--between women and men and among Latinos, African Americans, and Anglo Whites--are rooted in the legacy of class and political background and in experiences throughout the life cycle.

从交流和传播的视角解读越文化

本组讨论以越文化研究为例,探索地域文化研究的方法与视角。朱文斌一文检讨了当前越文化研究范式的局限,提出了范式转换的问题;陈越、梁涌两文分别从空间与时间的存在与发展上对越文化作了动态描述。其中,陈文从文化模式的角度,把越文化概括为“剑—书”文化;梁文则从交流与传播的角度,揭示了越文化的形成与发展。     

Theoretical consideration of effect of fishing mortality on growth and reproduction of fish populations

Summary An increase in fish mortality due to fishing can theoretically change the growth and reproduction of fish populations from the viewpoint of adaptation. We address the issue of how an iteroparous fish should convert surplus energy into somatic growth and reproduction at each age under given conditions of mortality. A model of life history, which maximizes the net reproductive rate using the discrete maximum principle, is improved employing a new relationship between body weight and surplus energy which we have recently proposed. The model is applied to the North Sea plaicePleuronectes platessa, for which it has been reported that the average length of young fish had increased whereas that of old ones had decreased for some decades. Although the model cannot directly explain the former phenomenon, the two phenomena can be interpreted as a change in the optimal life history due mainly to an increase in mortality.     

心中的牵挂

午后,沿着熟悉的小路,我慢慢走着。走进了这座城镇,便走进了我心中的牵挂……路两旁仍然是那一排排高高的梧桐树,树干那么直,那么粗,树冠那么大,它的叶子像一个个大手掌,它的果实像一粒粒小青豆。在夏季,梧桐树枝繁叶茂,张开着“大手掌”为我遮挡炎炎烈日。我喜欢行走在这些树荫里,微笑着看人们安静或嘈杂地从我身边走过。有如轻风吹过时,心神一爽。现在,两旁的梧桐树叶已变黄,秋天即至。眼前景色一片灿然。阳光从树中透出,细细碎碎的洒满一路,晃着人的眼睛。很美,但无可奈何地透着说不出的凄凉。一阵风吹过,凉凉地夹杂着几片梧桐树叶,…
