论东汉王朝对北匈奴的政策

于谓汉欺之 ,谋欲犯塞 ;谓宜还南所掠生口 ,以慰安其意。”章帝从袁安议 ,许之 ,令“度辽及领中郎将庞奋倍雇南部所得生口 ,以还北虏 ;其南部斩首获生 ,计功受赏如常科”。企图平衡南、北匈奴的关系。由上可知 ,在光武帝建武二十七年至和帝永元元年 (公元 5 1- 89年 )期间 ,北匈奴或因“惧于见伐” ,或因欲与汉合市 ,多次遣使求和亲 ,而东汉王朝则出于“冀其交通 ,不复为寇”的目的 ,与北匈奴保持了时断时续的通使、合市关系。当然 ,由于北匈奴时时寇边侵掠以及东汉王朝在处理南、北匈奴问题上的摇摆性 ,东汉王朝对北匈奴采取的以通使、合市…

Efe fathers: one among many? A comparison of forager children's involvement with fathers and other males

The study reported describes Efe (pygmy) forager one-, two-, and three-year-olds' involvement with males. The Efe of northeastern Zaïre were chosen because their social organization allows us to examine hypotheses based on studies in Western, technologically complex societies about the distinctive role fathers play in the lives of their young children. Behavioral observations of Efe children's day-to-day activities with fathers, men and boys were recorded using a focal subject sampling technique (Altmann, 1974). Two behavioral measures were created to capture the extent to which males were involved with children: Social engagement describes males' involvement with children and social attention describes eavesdropping by children on males' everyday activities. Eight one-year-olds, 7 two-year-olds and 8 three-year-olds were each observed for six, one-hour observation sessions that were distributed evenly over the daylight hours. Data were analyzed using the traditional measure of involvement (e.g., adult males) and using a newly developed measure of the involvement of the average individual (e.g., average adult mate). Comparisons at each of the ages showed that fathers were consistently like other men in the extent to which children participated in social activities with them and watched their activities. Only fathers' level of social engagement declined significantly as children grew older. Boys' role relative to other males became increasingly distinctive as children aged. The findings suggest that Efe fathers may not be unique in the same sense assumed by Western study ideals, and raise questions about the special status given to fathers in Western theory and data. The patterning of mate involvement with children is discussed in terms of Efe community life, and in terms of Efe children's developing understanding of their relationship with fathers and other males.
